Three members of the PSNI were injured when their vehicle was rammed in Derry this morning.
The officers had signalled for a car to pull over on the Buncrana Road at about 3.20 a.m. and pulled in front of it in a lay-by.
The police car was rammed from behind as the officers left their car. A spokesperson for the PSNI said all three officers were treated for minorinjuries.
Two youths were later arrested.
