A TAXI driver killed on a Fitzroy street just 30m from his house could be the victim of a spontaneous attack, police say.

Homicide Squad Detective Inspector Mick Hughes said Muktar Mahmud, 31, had just finished his shift when he was set upon by the attacker.

Five minutes later two people sitting in Condell Reserve, near the corner of Napier and Condell street, heard a faint cry for help.

A young man, with shoulder length fair hair, wearing dark clothing and carrying a satchel was seen running through the park.

“There is no suggestion he is involved, but he is certainly in the location,” Insp Hughes said.

“We ask him to contact police and come forward.”

Mr Mahmud suffered upper body injuries from an edged weapon.

Paramedics and police arrived at the scene and tried to revive Mr Mahmud, but he went into cardiac arrest and died at the scene.

“We know Fitzroy is a very cosmopolitan area, people are moving around at that time, we’ve had a couple of witnesses come forward,” Insp Hughes said.

Police would not say what weapon was used, but said the injuries were not inflicted by a gun.

No weapons have been found.

Ahmed Goud, a relative of Mr Mahmud, was told about his death this morning.

“I’m shocked,” he said.

“I pray for him and his family. All I know is he’s a nice guy, young boy, hardworking.”

Mr Goud said Mr Mahmud lived with his dad in Fitzroy.

He wasn’t married and didn’t have any children.

Police have reviewed CCTV in the cab and found Mr Mahmud had no passengers.

It’s understood he was not robbed.
