A man who rammed into a patrol car during a high-speed pursuit in Co Donegal badly injuring a Garda was drunk and uninsured.
Garda Marcus O'Dowd and Garda Barry Gallagher tried to stop thug John Tierney during the pursuit across Letterkenny.
The brave Gardai lined their patrol car across a road in a bid to stop Tierney from escaping while being pursued by other detectives in an unmarked patrol car.
