Residents on the street where Trainspotting 2 star Bradley Welsh was have spoken of their shock.
The founder of the Holyrood Boxing Gym, who appeared in "T2" as Doyle, was killed in suspicious circumstances in Edinburgh on Wednesday night.
Police said they were called to Chester Street in the west end of the city at around 8pm and found a man with serious injuries. He died at the scene.
On Thursday morning, a long stretch of the street remained cordoned off, with the stairwell of a downstairs flat covered by a large yellow sheet.
A floral tribute wrapped in a green and white scarf - the colours of Hibs Football Club - lay at the edge of the cordon.

Residents who live within the police cordon are being checked in and out of the taped-off area, but they say officers have told them nothing about what happened.
A woman, who did not want to be named, was in her flat across the road from the incident when she heard a "massive bang".
She added: "I was in the kitchen and heard a bang. I ran through to my boyfriend and said 'what was that?', because it sounded a little bit weird.

"Then there were loads of SWAT teams - the police were here super-quick."
Local resident Jessica Russel also told Forth Radio she had heard a gunshot.
She said: "Around 8, 8.30pm last night we heard a gunshot - what we assumed was a gunshot.
"I immediately looked out the window and didn't see anything. Maybe 10 minutes later police arrived.
"We looked out the window and everything was really frantic.
Lewis Starling, 25, said: "I just came home last night at about 8.40pm and the whole place was cordoned off.
"I had to get permission to get back to my flat and after that more people just arrived and it's just been locked down.
"It's quite surprising, you don't expect that around here."
He added that the yellow tarpaulin covering the entrance to the flat was put out at "about midnight or 1am".
Police said the death is being treated as suspicious and urged anyone with information to contact them.
