We can confirm the death of actor Glenn Quinn who played Doyle in Angel.

Glenn Quinn, who was 32, was found at the house of a friend on Tuesday. The exact cause of his death is currently unknown.

Quinn played Doyle in the first series of Angel, until the character made a dramatic exit in the episode Hero.

Glenn Quinn spent eight years playing Mark Healy in hit TV comedy Roseanne before joining the Buffy spin-off as Angel's half-demon mentor.

Born in Dublin, he used his own accent in the show, although writer Jane Espenson revealed that Glenn often had to re-dub his own dialogue in post-production if it sounded too incomprehensible to an American audience.

As well as acting, Glenn owned a night club in Los Angeles and taught David Boreanaz to play the drums.

We'll bring you more details as we get them.
