Man found dead in Sydney street 'behind break-in gone wrong'

New details have revealed what led to the murder of a man in a street in Sydney’s inner west, metres from a primary school.

Pictures have been released of the immediate aftermath of the death in Forest Lodge, showing a balaclava, fake gun and knuckle dusters on the road.

Detectives are investigating whether the murdered man was behind a suspected home invasion turned deadly.

“I heard a woman in the street yelling out ‘don’t’ and screaming. And I just rushed out thinking she was being attacked,” witness Lynne Charlesworth said.

“When I came out of the house I saw a man slumped in the street covered in blood.”

Witnesses say they heard a woman scream “who are you” moments before the attack.

It is believed the 30-year-old victim tried to gain access to a Hereford Street home.

Ms Charlesworth watched the aftermath, horrified at the scene that played out.

“He got to our car, laid back on it. He then pulled himself up and thats how the car got covered in blood,” she said.

Witnesses told 7 News a man and woman chased the victim from a house and when they caught up with him the man struck the victim multiple times in the head with a Samurai sword.

It’s understood the victim also lived on the same street.

Police say the trio was known to each other. The man and woman are still on the run and investigators say they know who they are and it won’t be long before they catch up with them.

They’re described as Caucasian and both in their 20s. The woman has bleached blonde hair, while the man’s is short and brown.
