A man has been arrested in connection with the death of T2 Trainspotting actor Bradley Welsh.
The 48-year-old was shot as he walked down the stairs to his Edinburgh flat on Wednesday.
Police Scotland said on Tuesday a man has been arrested in connection with his death but has been released, pending further inquiries.
Mr Welsh's partner and young daughter were at home in the Chester Street flat when he was targeted.
Welsh starred alongside Ewan McGregor, Ewen Bremner, Jonny Lee Miller and Robert Carlyle in T2 Trainspotting, playing gangland figure Mr Doyle.
As well as appearing on film he was involved in charity projects in Edinburgh, including helping young people to stay away from a life of crime through his Holyrood Boxing Gym.
Following the shooting, Trainspotting writer Irvine Welsh paid tribute to his "amazing" friend online.
He 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."
