A man has been arrested in connection with the killing of the T2 Trainspotting actor Bradley Welsh in Edinburgh last Wednesday evening.
The 48-year-old former boxing champion and reformed football hooligan was killed on the doorstep of his home while his wife and young daughter were inside.
He was shot in the head as he walked downstairs to the family’s basement flat in what police believe was a targeted attack.
Last week, the author Irvine Welsh led tributes to Welsh, who starred alongside Ewan McGregor, Ewen Bremner, Jonny Lee Miller and Robert Carlyle in T2 Trainspotting, playing the role of gangland figure Mr Doyle.
The man has been released pending further inquiries.
A Police Scotland spokesperson said: “This investigation is continuing and anyone who has information, but has yet to come forward, is asked to do so immediately.”
