Police have released CCTV footage and a composite image of a possible suspect in the murder of a taxi driver almost one year ago.

Mohamud Muketar was stabbed 30 metres from his home in Fitzroy, Melbourne, in what police believe to have been an unprovoked and random attack.

The 31-year-old was found alive on the corner of Condell and Napier streets soon after at 11:30pm but died at the scene.

Police are renewing calls for anyone with information to come forward, releasing a composite image of a possible suspect in the attack using descriptions provided by witnesses.

Mohamud Muketar's father desribed the 31-year-old as happy and contented.

Two people sitting on a park bench across the road heard Muketar's cries for help and then saw a slim man approximately 183cm tall with light, shoulder-length hair running past them, according to The Age.

The man was seen running north east through Condell Reserve and then continuing north along Wood Street.

At the time, he was wearing a dark top and dark pants, which may have been jeans, and was carrying a 'Country Road-style' duffel bag, police said.

New footage has also been released, showing a white Toyota Yaris, seen circling the area and stopping in a nearby alleyway several times about 10 minutes after Muketar was murdered.

Police say they haven't found a link between the driver of the car and the murder, but hope that anyone in the car at the time may be able to provide more information about the night of the murder.

Footage has been released showing a white Toyota Yaris, believed to be a 2014 or later, which was seen driving in the area shortly after Muketar was killed.

"It's been nearly a year since Mohamud's death and sadly we've not been able to tell his family that we've caught who did it," Homicide Squad Detective Senior Sergeant Stephen McIntyre said.

The CCTV footage shows that there were people in the area at the time who haven't come forward to speak to police, McIntyre said. He is urging anyone with any information -- no matter how seemingly insignificant to the murder -- to come forward.

"Those people may not think they have information that is of any value to police or that they didn't see anything, however we know from past experience that even the most minor detail can make a huge difference in an investigation like this."
