A Garda was injured and a patrol car damaged after a pursuit in Co Donegal.
A Silver Hyundai i-30 van with a 142 Meath registration plate, collided with a stationary patrol car around 4.30pm yesterday.
The incident happened after Gardaí encountered the van acting suspiciously and being driven dangerously.
During the course of this incident, the van then collided with a second patrol car, which was stationary at the time.
The van then crossed the border into Northern Ireland at Lifford.
The van has since been recovered by the PSNI.
Gardaí are appealing to the public for information or video footage in relation to the movements of this vehicle prior to the incident in St Johnson.
Anyone who may have observed a van matching this description is asked to make contact with Gardaí in Lifford on 074-9141000 or the Garda Confidential Line on 1800 666 111.
The driver of the patrol car suffered minor injuries.
Investigations are ongoing and no arrests have been made to date.
