A post-mortem examination is to be carried out on the body of a man found in a house in Co Carlow this morning.

The Polish man was found by ambulance personnel at the bottom of a staircase in a house on Main Street in Bagenalstown at about 12.15am.

It is understood the man, whose name has not been released by gardaí, lived in a house on Kilcarrig Street.

He was in the house on Main Street overnight with a number of other men.

The men had been drinking and it is believed one of the people living there contacted the emergency services after midnight to say the 25-year-old had suffered injuries after falling down the stairs.

The scene of the incident was preserved this morning and the man's body was brought to Waterford Regional Hospital.

Assistant State Pathologist Dr Khalid Jabbar is to carry out the post mortem.

Detectives are awaiting the results of the examination before deciding on the direction of the investigation into the man's death.

However, one officer involved in the inquiry said that, while the incident is officially being treated as "suspicious", gardaí do not expect the autopsy to indicate that another person was involved in the death.
