Trainspotting 2 actor Bradley Welsh was shot dead on the doorstep of his home while his partner and young daughter were inside, police have said today.
A murder investigation has been launched into the death of the 48-year-old father after he was killed by a bullet to the head as he was walking down the stairs to his Edinburgh flat.
An anonymous ex high-ranking officer has also come forward and claimed Welsh was "a guy you'd call a ken-speckled character" who had a "few enemies".
Police were called to Chester Street in the west end of the city at around 8pm on Wednesday after multiple reports of a gunshot.
A neighbour who heard the gunshot, found Mr Welsh fatally wounded outside his flat but it was only once police arrived that his family learned of his "horrific death".
Detective Superintendent Allan Burton from the major investigation team said: "We have a lady who's lost a partner, a child who's lost a dad, a family who have lost a son and brother.

"And so, for their sake, and the sake of everybody else in this community, please come forward and help us find the person responsible for this horrific death.
"Mr Welsh's partner and young daughter were in the house at the time when this took place.
"Thankfully they were unaware - they never heard the bang, if you like."
He added: "When the police arrived, that's when the knowledge and horrors of losing Bradley to them had become real.
"They are devastated. We will support them as best we can, with specially trained family liaison officers, and we'll continue to do that over the coming weeks and months in preparation for any future trial.
"But it's not sinking in just yet, it's going to take time.

"Their whole world has been turned upside down by the actions of an individual last night."
Detectives believe Mr Welsh was shot in a targeted attack by a man who fled the scene on foot.
In a plea for witnesses, Mr Burton called for people who "have got any information, or have heard any rumours or speculation, or know someone who's acting differently after the events of last night and are suspicious of this individual - please come forward".
Dozens of forensics officers were searching Chester Street and neighbouring roads within the large police cordon.
Dt Sup Burton added: "We'll be looking to see if anything has been dropped, discarded, someone's been standing by waiting for Mr Welsh to return.
"Any cigarette butts, cans, etc could indicate the presence of any individual.
"We will be conducting a fingerprint examination of the railings and premises and fixed furniture round about the entrance to the apartment, looking for fingerprints and DNA.

"We'll be doing a full forensic examination of Mr Welsh's apartment to see if there's anything in the flat that might give us an indication of the motivation and why he has been targeted."
Welsh starred alongside Ewan McGregor, Ewen Bremner, Jonny Lee Miller and Robert Carlyle in T2 Trainspotting, playing gangland figure Mr Doyle.
He also appeared in an episode of Danny Dyer's Deadliest Men in 2008.
Irvine Welsh, the author of Trainspotting, 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."
Mr Welsh was also involved in charity projects in Edinburgh, including helping young people to stay away from a life of crime through his Holyrood Boxing Gym.

Bunches of flowers, cards, teddy bears and football scarves in the colours of Mr Welsh's beloved Hibernian were laid at the edge of the police cordon by friends and family.
Builder Morgan Currie, 20, visited the scene of the shooting and said: "I knew him through his charity work.
"He was a gentleman every time I saw him, no matter what and with anybody.
"With all the charity work, with all the amazing stuff for homeless people, he was just a true gentleman.
"He just kept his head down, looking after his kids and his fiance. He's a family man and just loved doing his charity work.
"When I heard about it this morning I got a fright, I was like 'oh my God'.
"It's not sunk in yet."

The shooting has had a "profound impact", according to Chief Inspector David Robertson, who said: "I'd like to reassure the public that murders in Edinburgh are extremely rare, the use of a firearm even more so.
"Edinburgh remains a safe place to live, work and visit.
"As local area commander, I recognise the profound impact that this incident has had on Mr Welsh's family, his friends and on the wider community.
"I'd like to take the opportunity to offer my sincere condolences to them and officers will be providing additional patrols, additional reassurance and carry out investigations over the coming days.
"We've put in place a significant major investigation with significant resources and we are doing everything we can to identify those responsible and bring them to justice swiftly."
Meanwhile, a former top police officer has described Welsh as a "ken-speckled character" whose criminal connections would now be looked into.
The Edinburgh Evening News reported that a former police officer believed the death of Welsh could be solved within a day.
Speaking to the newspaper, the ex high-ranking officer said: "He was a guy you'd call a ken-speckled character.
"He had a lot of connections.
"He was some-time showbiz and a part-time actor, but at the same time he had a lot of criminal connections. When you live a life like that, you're going to have a few enemies.
"The police will be going through the motions, trying to piece together what happened."
He added: "They'll be looking at his latest movements, any threats, looking at his criminal associates.
"Most of these cases are done and dusted in the first 24 hours and I wouldn't be surprised in that's the case."
