A man has been fatally shot at a home in Sydney’s west that also had two young children inside.

Emergency services were called to a property on Bruce Street, in Merrylands West, about 3.15pm on Wednesday following reports a man was shot in a driveway.

It’s understood the man was hit in the head in a drive-by shooting. Witnesses reported hearing up to eight gunshots, and paramedics attempted to revive him but he couldn’t be saved and died at the scene.

He has not been formally identified, but is believed to be aged in his 40s, and police said a grey Audi was seen leaving the area.

A crime scene has been established and an investigation into the circumstances surrounding the incident is underway.

Footage shows a work ute parked out the front of the house, with unconfirmed reports an electrical contractor, known to the occupants, was visiting the house and that the shooting could have been a case of mistaken identity.

‘People associated with this address have links to organised crime,’ Detective Superintendent Simon Glasser said.

‘It is a possibility that the wrong person has been shot by these offenders.’

The news follows another fatal shooting in Glen Alpine, south-west Sydney, at 4am on Tuesday.

Marco Tapia, 23, was fatally shot in the neck and arm in his bedroom after three masked men broke into a Mount Sugarloaf Drive home.

The unknown offenders fled the scene and remain on the run.

The young man was not known to police and had nothing more than a traffic offence on his record.

Detectives are considering whether it was also a mistaken identity hit.

‘Popped the wrong person. Didn’t even get the right house,’ Iziah Utai, an alleged member of the Coconut Cartel, wrote online after that shooting.

He returned on Wednesday to add: ‘RIP Marco. #innocentvictim’. 

The Alameddine network, a notorious crime syndicate, and the Coconut Cartel, an emerging crime-for-hire gang, have allegedly become embroiled in a feud, spilling into shootings across Sydney in recent months.

Campbelltown Acting Superintendent Gretchen Atkins on Tuesday said she was aware of online posts and said everything was under consideration.

NSW Opposition Leader Kellie Sloane said the incident showed gangland violence was once again out of control.

‘We need to be very clear about the threat on our streets and that is dangerous organised criminals … innocent people have been in the firing line way too often,’ she said.
