The Garda Síochána Ombudsman Commission is investigating a road crash in which a man died last night.
The incident occurred at Dunmore in Co Galway, which is some 13km from Tuam.
A 22-year-old man died when his car left road at around midnight.
The commission, which investigates incidents involving members of the force, said the matter was referred to it under section 102 of the Garda Síochána Act 2005 "as a garda car was in the vicinity at the time" of the crash.
The commission last week began an investigation into a collision in Co Limerick in which two men were killed by a car driven by an off-duty garda.
