The man shot dead in a Dublin pub last night has been named.

32-year-old Declan Griffin with an address in Ballyfermot in Dublin was a convicted drug dealer.

Gardaí believe he was murdered because he was a garda informant.

The Horse and Jockey pub, where he was shot, remained sealed off today for forensic examination.

Mr Griffin was taken off a life support machine and pronounced dead in St James's hospital early this morning.

Gardaí believe the gunman was in his forties. He walked into the pub five minutes after Declan Griffin, shot him once in the head and ran away.

Mr Griffin was known to gardaí as a drug dealer with a lot of enemies.

He made mortal enemies after admitting in a Dublin court four years ago that he was a garda informant.

He was found not guilty of bringing over E1m worth of drugs into Dublin Airport from Amsterdam after he claimed the operation was cleared by his garda handler.

Gardaí believe they saved his life twice, once by arresting a Northern Ireland hitman in Lucan and again a few weeks ago when the ERU arrested a man in West Dublin.

Griffin was carrying a gun and wearing a bullet proof vest when he was shot.
