Gardaí have launched a murder investigation into the death of Monaghan man Seamus Bell following a post-mortem examination this afternoon.

The 36-year-old man who was left in a coma after an alleged assault in January has died in hospital.

Seamus Bell, of Foxfield, Carrickmacross, was pronounced dead yesterday evening at Our Lady of Lourdes Hospital in Drogheda.

Mr Bell had been in hospital since the alleged assault at Main Street, Carrickmacross, Co Monaghan on 20 January 2018.

Professor Marie Cassidy carried out a post-mortem examination this afternoon.

After receiving the results, gardaí said they are now investigating a murder.

A 34-year-old man was arrested on 21 January connection with the investigation.

He is currently in custody in Cloverhill Prison and is due to appear in court on 21 June.

Local charity fundraising group Carrickmacross Lions tweeted its sympathies to friends and relatives of Mr Bell.

The group had set up a support fund earlier this year for father-of-three Mr Bell, who was a fitness instructor and local GAA player, and his family.
