Two gardaí were treated in hospital today after another vehicle allegedly rammed their patrol car in a head on collision in Limerick.
The officers, who were travelling in an unmarked car, were responding to a 999 call regarding a domestic dispute when the incident occurred.
The unmarked car entered an estate in Castletroy at around 1pm. When the officers came on the scene, a gold-coloured Rover, collided head on with their Toyota Corolla.
Extensive damage was caused to the front of both vehicles.
Back up gardaí were then drafted in to deal with the incident.
Both injured gardaí were taken from the scene by ambulance and treated for shock. A female Garda was treated for serious injuries to her neck and back before being discharged.
A man, who was travelling in the Rover vehicle, is believed to have lost consciousness following the collision, but was in a stable condition last night.
He had been treated by paramedics at the scene earlier for a head wound.
The office of the Garda Ombudsman is investigating the incident and can be contacted on 1890 600 800.
Separately, a man has been arrested after a Garda car was rammed in the course of its pursuit of another car in Dublin last night.
Gardaí in Rathfarnham attempted to stop a car at Daltree Place, Ballycullen at about 10.15pm last night, a Garda spokesman said.
"During the course of this operation the Audi car rammed the Garda patrol car. The three occupants fled from the Audi and were pursued by gardaí."
A 25-year-old man was arrested a short time later and a firearm was recovered. He is currently detained at Rathfarmham Garda station under Section 30 of the Offences Against the State Act 1939.
Investigations are continuing, the spokesman said.
