Police are searching for a group of people over a one-punch assault in Subiaco.

POLICE have urged a group who left a Kinglsey man in an induced coma after a one-punch assault to come forward.

The 29-year-old was found by police officers on Hay Street in Subiaco at 12.20am on Saturday morning after the attack.

Perth City detectives say the man had been punched by an unknown man, who then ran away.

The man remains in a serious condition in Sir Charles Gairdner Hospital.

It was reported the victim was 29-year-old musician Sasha Tostevin. His friends said Mr Tostevin did not have a violent bone in his body and would be devastated if his “genius” musical talents were affected by the assault.

Detectives would like to speak to a number of people they say may be able to assist with their investigation.

They have released CCTV footage showing the group walking past moments after Mr Tostevin was attacked.

Mr Tostevin’s father told Nine News: “You don’t want this to happen to your own family but this time it has and it’s terrible.”

The five people who were caught on CCTV footage are described as:

● Male, wearing a black long sleeve jacket with white under hood.

● Male, wearing denim vest with long sleeve light coloured arms

● Male, wearing short sleeve white T-shirt with denim sleeves and denim front pocket

● Female, wearing a bright yellow dress

● Female, wearing a white top and tight black pants

“We are asking members of this group to come forward and make contact with the detectives via Crime Stoppers,” a WA Police spokesman said.

The assault is the second such attack in as many weeks, after another 29-year-old man was found unconscious on the footpath in Lake Street, Northbridge, by police officers last Saturday morning.

The man was allegedly assaulted by three men and received serious head injuries.

Anyone with information of the two assaults should call Crime Stoppers on 1800 333 000.
