A serial Tube sex attacker has been found guilty of murdering two women and almost killing a third while on police bail.
Simon Levy, 40, suffocated Carmenza Valencia-Trujillo, 53, in March 2025, before using the same method to kill Sheryl Wilkins, 39, five months later.
He has also been found guilty of violently raping another woman in January last year, whom he left for dead.
Detectives now believe Levy may have claimed scores of victims while he was on bail, carrying out daily attacks for years, escalating from groping women on the London Underground to rape, suffocation and eventually murder.
Now, as Levy faces the rest of his life behind bars after being convicted of murder and rape, it can be revealed how police, prosecutors and probation services missed a monster in their midst.
In an appalling betrayal of victims, despite him having a shocking record for sexual violence dating back to 2018, British Transport Police (BTP), the Metropolitan Police, the Crown Prosecution Service (CPS) and magistrates all failed to protect the public, releasing Levy on bail four times in a series of failures.
It left him free to stalk the transport network daily, claiming countless victims.
While on bail Levy carried out at least six sexual assaults on the Tube, raped and suffocated a sex worker leaving her for dead, and killed two other women in a two-year rampage.

Levy has now been convicted of carrying out two murders, two rapes, a near-fatal suffocation and 13 sexual assaults
In total, Levy has now been convicted of carrying out two murders, two rapes, a near-fatal suffocation and 13 sexual assaults.
Now there are calls for a public inquiry into the scandal as campaigners say the case makes a mockery of police and CPS promises to tackle violence against women and girls in the wake of Sarah Everard’s murder by Scotland Yard officer Wayne Couzens.
And police believe there are many other women who have not yet come forward.
The partially blind offender was first jailed for three years in 2021 for carrying out sex attacks on two women at Notting Hill Carnival and a Camden street party in 2018.
But even in jail he continued to target women, groping a prison officer in 2022.
When he was released early at the halfway point of his sentence in February 2023, Levy told probation staff that sex workers were frequently offering him services, yet he claimed to never leave his home due to his eye condition.
In reality, Levy was still on licence in October 2023 when he started venturing on the tube for prey, roaming stations across London at peak times when he knew carriages would be packed with passengers, leaving victims unable to escape his clutches.
He regularly tied a jumper around his waist to hide his wandering hand as he grabbed the women around him.
In May 2024, he was recalled to prison following a rape allegation while the case was being investigated.
He was released in August the same year, after which he continued his campaign of attacks on the Tube. His youngest victim was 18, and his oldest 32.
Levy, who has learning difficulties, was supposed to be supervised by both probation and police visor (violent and sex offender register) staff.
But his chilling fascination with rape and murder went unnoticed as he secretly amassed a huge collection of newspaper stories about notorious offenders he lionised, including black cab rapist John Worboys, paedophile Jeffrey Epstein and Harvey Weinstein.

Levy was arrested in November 2024 for two sex attacks on the Tube. During one of these incidents, in October, the victim recorded Levy on her phone, capturing him assaulting herself and another woman.
However, a blundering BTP officer delayed doing basic ID checks for weeks, opting instead to extend his bail.
BTP Detective Chief Superintendent Pete Fulton later admitted: ‘The officer just wasn’t getting a grip on their workload. It was incompetence, to be honest.
‘The supervisor was pretty passive in that process as well.’
On arrest, Levy was found to have a TFL staff Oyster card, which had been reported missing by a bus driver months earlier.
It allowed him to travel for free across the capital, to continue his campaign of attacks.
Incredibly, BTP decided to hand the card back to Levy, unaware at the time, they say, that it did not belong to him.
This mistake only emboldened Levy who decided to carry out his first rape on the same night he learnt his bail had been extended on January 21, 2025.
In a brutal attack, he jumped on a prostitute, breaking her collar bone before raping her. He suffocated the woman, leaving her near death, with one hand squeezing her neck, and the other covering her face with a finger down her throat.
Four days later, she pointed officers towards the exact location of Levy’s home, but she was never formally interviewed as she was withdrawing from drugs.
On March 17 Levy struck again using the same tactic.
The body of Carmenza Valencia-Trujillo was found face down in a stairwell of a disused block of flats in Southwark, south-east London.
The 53-year-old drug user’s neck had been compressed, her face smothered and a pipe smeared with his blood was found beside her, the court heard.
The TFL staff Oyster card showed Levy’s travel to the scene.
Yet days before Levy was arrested on April 1 over the murder, he told police visiting his home as part of routine convicted sex offender checks that he never went out.
It was a blatant lie that a simple police computer check would have exposed as Levy was on bail at the time for a series of sex attacks on the tube.
Scotland Yard decided to release him on bail after the cause of Ms Valencia-Trujillo’s death was deemed to be ‘unascertained’ in a post-mortem examination.
After learning of his arrest for murder, BTP officers procrastinated, deciding to do a risk assessment and extend his bail to May 1, instead of arresting him for further offences on April 3.
Levy reacted to the news by accelerating his offending, carrying out four further attacks on the underground before he answered bail on that date.
On May 2, he was charged with five sex assaults on the tube and was remanded in custody overnight.
But astonishingly he was released on bail by magistrates even though he was also suspected of murder.
In an appalling blunder, the CPS has now revealed that prosecutors failed to oppose bail and they cannot recall if the court was told about the murder investigation or his prior offending.
Yet BTP had warned prosecutors at the time: ‘Levy’s offending appears to be escalating in terms of frequency.
‘He’s considered by police to be a danger to the public and at high risk of reoffending. Police have significant concerns that if granted bail, Levy will continue in his predatory offending.
And reiterating their concerns: ‘It is firmly believed that Levy has a total disregard for bail conditions and that if granted bail there is a high risk of him re-offending against/sexually assaulting women and girls.’
Levy failed to show up at court when he was charged with a sixth sex assault charge on June 3, but no warrant was issued.
Three weeks later he was spotted on the underground by a BTP officer and charged with breaching his bail condition by going on the tube, failing to appear at court and committing two sex attacks at Charing Cross and Westminster station.
Jurors were told that Levy was earlier this year convicted of 11 sexual assaults, carried out between April 2022 and May 2025
Incredibly when he appeared at court, Levy was granted bail again.
He failed to attend further hearings on July 18 and August 11, yet no warrant was sought for his arrest.
Again, the CPS failed to tell the court that Levy was under investigation for murder, leaving him free to commit another killing days later.
On August 28, Levy claimed his second murder victim, smothering Sheryl Wilkins, leaving her body in the same location as the earlier rape attack, just minutes from his own home.
Police arrested him on September 5 after he was identified at the scene on a facial recognition camera.
He was remanded in custody three days later.
In February this year Levy was convicted of carrying out 11 sexual assaults between April 2022 and May 2025 – mostly of which were the Tube attacks on young women.
The prosecution was kept secret for fear of prejudicing Levy’s subsequent murder trial, which ended today.
Now furious victims have hit out at the criminal justice system, asking: ‘Who is there to protect women and girls?’
The Daily Mail can reveal that no officer has lost their job as a result of the blunders in the Levy case, although one BTP officer has been removed from investigative duties.
The Met has referred itself to the Independent Office of Police Conduct (IOPC).
BTP has not referred itself, saying: ‘It was dealt with. It was a performance issue, not a conduct issue.’
Ahead of the verdict, Met Deputy Assistant Commissioner Kevin Southworth claimed that police were ‘quick’ to realise their errors, adding: ‘We’re very quick to hold ourselves to account, quite rightly in the way the public would expect.
‘So we’ve self-referred to the IOPC to answer those questions: What did our officers know, and what should they have done if they didn’t do it?’
Describing him as ‘a prolific predatory monster’, he said: ‘The offending of Simon Levy is amongst the most harrowing we’ve seen in recent times… While there were multiple investigations, ultimately the collective system failure, and his bail reports, left him free to go on to offend in the most harrowing manner imaginable.’
Despite committing almost daily attacks, he admitted that Levy didn’t ’stand out’ to police at the time from the 10,000 registered sex offenders in London.
The double killer, who also used the aliases Levi and Shamus, was never on the Met’s ‘V100 list’ of the most dangerous offenders to women and girls.
Mr Southworth said: ‘While we know now Levy is one of the most dangerous offenders we have encountered in recent times, by spring last year he was one of many people on the registered sex offenders list, but not necessarily one that would have stood out.’
The number of sex offenders being managed in the community grew by 1,000 in the last year alone.
‘All of that adds up to one unfortunate, immutable truth, which is we have a very high number of sexually violent people, that is incredibly challenging to manage,’ Mr Southworth admitted.
‘We face unfortunately a very vast and rising tide of sexual violence. What has stood this man out now to us all is the acceleration in his offending.’
When asked whether the deaths were preventable, he said: ‘I think the obvious conclusion is that if Levy had been remanded at that point, he would not have been able to go on to commit, at the very least, the murder of Sheryl.’
Mr Fulton said of BTP’s errors: ‘I can’t say there’s not another offender like Levy out there. There possibly is, but we have learned valuable lessons.’
Lisa Ramsarran, Chief Crown Prosecutor for the CPS, said: ‘There was relevant information that was not provided to the court when bail applications were being considered.
‘We cannot know what decisions the courts would have made had different or stronger representations been advanced. But we recognise our responsibility and we are sorry for the shortcomings.’
Harriet Wistrich, chief executive of Centre for Women’s Justice, told the Daily Mail’s podcast: ‘It is a very, very shocking case in terms of the number of opportunities there were to have stopped him.
‘We end up with two women dead, two children who’ve lost their mother and families that have lost their loved ones as a consequence of failures.
‘After all the so-called lessons supposed to have been learned following the Worboys case, we were told that this would not be repeated.
‘Then obviously following some of the recent terrible cases involving police perpetrators like Couzens and Carrick.
‘That still, this kind of level of routine failure at every stage, and not just the police, but the courts as well – not remanding him, not issuing warrants for his arrest when he failed to appear given what was known about the type of offending and the escalating offending- it just very sadly inspires a complete lack of confidence in our criminal justice system.
‘At a time when women are rightly very concerned about the decision by the Government to early release serious sexual offenders, we are supposedly assured that they will be monitored tightly when they are released.
‘How can any of them have any confidence whatsoever that they will be safe?’
She warned that Levy was unlikely to be the only case where predators are slipping through the net.
‘There must be an independent investigation, if not a public inquiry into this case because of the scale of the failures.
‘Because these things just keep happening again and again. Something very radical has to change.’
Latest figures show that reported sexual offences on the London Underground have reached their highest level in five years.
There were 595 sexual offences in 2024-25 and this year has seen a 28 per cent rise in sexual assault reports on the tube.
Police chiefs fear that Labour’s soft justice reforms will make matters worse as forces are under pressure not to remand offenders in custody.
The National Police Chiefs Council has estimated that the Government’s sentencing reforms to jail fewer offenders by ditching shorter prison sentences and releasing inmates earlier will lead to a six per cent surge in crime.
Britain’s top officer Sir Mark Rowley recently warned: ‘We’ve got extraordinarily prolific and dangerous offenders who there would not have been any doubt about, even a couple of years ago, we would have been remanding in custody.
‘They are now being bailed and repeatedly bailed, then repeat offending and that troubles us greatly.
‘The system across the country is struggling.’
