A garda had to be cut from his patrol car after it was rammed following a high-speed pursuit in Co Donegal early on Friday.
The collision happened at McGrory's Brae, between Ballybofey and Donegal town, when a black Fiat Punto crashed into a garda car.
The Punto had been pursued after failing to stop for gardaí in Donegal.
It is unclear if a stinger-style device was deployed in a bid to stop the car. The garda inside the patrol car was cut free by fire crews and was taken to Letterkenny University Hospital for treatment for minor injuries.
The driver of the Punto remains in hospital and gardai are waiting to interview him.
A Garda spokesman said the Ombudsman attended the scene as a matter of routine but are not investigating the incident.
He said gardai were appealing for anyone who saw the Punto on the Barnesmore Gap early on Friday to contact Letterkenny Garda station at (091) 67100 or the Garda Confidential Line 1800 666 111.
