Gardaí investigating the murder of a man in Limerick say there is no apparent motive for the killing.

Chief Superintendent Kevin Donoghue said a preliminary examination has indicated that the victim was shot with a handgun and not a shotgun.

Gardaí have appealed for information from anyone who was in the Kiltreagh housing estate last night who may have seen anything or anyone acting suspiciously.

In particular they are looking for details of the movements of a dark coloured Renault Espace car which was found burned out this morning in the Rosbrien area of Limerick, and which they believe may have been used in the killing.

Gardaí believe the man may have been a victim of mistaken identity.

He has been named locally as 28-year-old Shane Geoghegan who was a prominent player with Garryowen Rugby Club, where he captained their thirds team.

Gardaí responded to a 999 call after local people heard a number of shots in the Kilteragh housing estate shortly after 1.30am.

Following a search of the estate, they discovered the body of a man at the rear of a house in the Clonmore area.

A wide area around the scene where the body was found was sealed off and a technical team as well as the State Pathologist Dr Marie Cassidy were called in to assist with the investigation.

Gardaí have established that the victim had visited friends in the estate to watch the Ireland-Canada rugby match and was on his way home when he was shot.
