CCTV has been released as part of an ongoing investigation into the alleged fatal stabbing of a man in Sydney’s southwest.

James Pakis, 34, was found with multiple stab wounds at a home on Lakemba Street in Belmore on March 15.

Police were initially called to the home following reports of a concern for welfare.

A 24-year-old man was also at the home at the time and was providing medical assistance to Pakis.

He was taken to hospital for treatment under police guard and later attended Campsie Police Station where he was released without charge.

Two days later, detectives arrested a 21-year-old man at Bankstown Police Station and charged the young man with murder.

He remains before the courts.

As the investigation into Pakis’ death continues, police have released CCTV in the hopes a member of the public will come forward with information.

The first piece of footage shows a man wearing black clothing and carrying a blue bag. In the video, he is being picked up by a car on a street near the crime scene on the day Pakis was allegedly murdered.

The car is described as a black Honda Jazz, which has damage to its rear windscreen.

Further CCTV shows the car, which had damage to its front, driving and parking in a carpark a few hours before the incident.

Detective Inspector Craig Brooks said police have ruled out organised crime, domestic violence and drug-related crime as potential theories for Pakis’ death.

Pakis had no criminal record.

Brooks said police had exhausted all options and were only now releasing the footage as they needed help from the public.

“This is a horrific offence,” he said.

“James lost his life. He was a young 34-year-old man and obviously we want to see justice for his family.”

No piece of information is too small, Brooks said.

“Anyone who recognises this vehicle or has any information on its whereabouts is urged to come forward.”
