The Garda Síochána Ombudsman Commission is investigating a road crash in Co Limerick in which a 17-year-old boy was killed and three people were injured.

The teenager died when the car he was travelling in - a 05 D registered Mazda 6 - hit a ditch at Tubberyquinn, Ballyneety, shortly after midnight.

He has been named locally as Gearóid Sheehy-Ahern, who was from Greenmount Avenue in the Ballinacurra Weston area of Limerick city.

Gardaí say three other males were injured, one seriously. They are all being treated at University Hospital Limerick.

In a statement, gardaí said the incident was referred to GSOC "as a result of earlier interaction between the crashed car and gardaí."

They have appealed to any witnesses to the crash or anyone with information to contact Roxboro Garda Station on 061-214340.
