Trainspotting 2 star Bradley Welsh has been shot dead in Scotland, according to reports.
The actor, who also appeared in an episode of Danny Dyer’s Deadliest Men, was reportedly killed in Edinburgh on Wednesday.
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.
Police Scotland said: “His death is being treated as suspicious and inquiries are continuing.
“Officers will continue to provide a high-visibility presence in the area to engage with the public, offer reassurance and gather information that can assist with this investigation.
“Anyone who believes they have any relevant information should contact police immediately.”
Welsh, 42, starred alongside Ewan McGregor, Ewen Bremner, Jonny Lee Miller and Robert Carlyle in T2 Trainspotting, playing gangland figure Mr Doyle.
The writer tweeted: “Bradley John Welsh, my heart is broken. Goodbye my amazing and beautiful friend.
“Thanks for making me a better person and helping me to see the world in a kinder and wiser way.”
The actor appeared in Danny Dyer’s Deadliest Men in 2008, where he described himself as a “born leader” in the episode.
Welsh later became involved in charity projects in Edinburgh, including helping young people to stay away from a life of crime through his Holyrood Boxing Gym.
Welsh was reportedly a former British ABA Lightweight boxing champion.
Other people also paid tribute on social media, with one woman posting a picture of herself and friends alongside Welsh in a boxing ring.
She said: “You to me are treasure, you to me are dear. Our coach, our motivator but most importantly our friend, Brad Welsh.”
One man described Welsh as a “huge character” in Edinburgh.
He said: “Devastating news about Brad Welsh tonight, a huge character in Scottish amateur boxing and the Hibernian support and someone who contributed a great deal to society through his charitable work and boxing gym. RIP.”
Writing on social media, local resident Alasdair Morton said armed police were “all over” the area.
He tweeted: “Armed police all over Chester street. Road closed off. We have been told to go inside. Before doing so we heard the police say to the National incident response unit – gunshot would (sic) to the head.”
