Simon Carlyle, the creator of BBC sitcom Two Doors Down, has died. He was 48 years old.
The BBC has reported that Carlyle's manager, Amanda Davis, said "I am immensely sorry to confirm that Simon Carlyle has died at the age of 48".
The sitcom has starred Arabella Weir, Kieran Hodgson, Alex Norton and others, and was also created and written by Gregor Sharp.
Carlyle from Ayr wrote the show as a one-off in 2013. It was commissioned as a series in 2016.
Louise Thornton, head of commissioning at BBC Scotland, said staff were "deeply saddened" to hear the news.
She added: "Simon was a major writing talent, loved for his work on Two Doors Down and many other series.
"Our thoughts are with Simon's family and friends, and the cast and crew on Two Doors Down."
Jon Petrie, director of comedy commissioning at the BBC, said "His warm comic voice shone through these characters, garnering huge audience affection, and firmly establishing it as a long-lasting sitcom favourite," he said.
Two Doors Down was recommissioned for a seventh series in February and is due to move to BBC One for the next six episodes of the new series. It has not been confirmed if the new series will still be broadcast as planned.
The sitcom's production team said: "We are deeply saddened by this terrible news. Simon was a brilliant, funny, mercurial and magnificent human being.
"He was at the centre of all the work we made together and his loss will be felt profoundly by all of us."
Carlyle also wrote for ITV comedy Changing Ends and LGBT+ show Boy Meets Girl.
All previous series of Two Doors Down are available to watch on BBC iPlayer.
