Police want to interview a man in connection with the death of a 19-year-old man, who was assaulted twice during a night out in Omagh, Co Tyrone.

Jason McGovern, from Tydavnet in Co Monaghan, was punched at a bar in Omagh at about midnight.

He was punched again about two hours later outside another licensed premises on the Kevlin Road.

Mr McGovern managed to make his way home to Emyvale in Co Monaghan, but was found dead at a house in the village at about 12pm yesterday.

Police believe the young man was attacked by a stocky man with red or blonde hair.

A post-mortem has been carried out at Our Lady's Hospital in Navan.

Gardaí and the PSNI are investigating his death.
