Bomb thrown at van outside Co Armagh home
The device was detonated in the Ardaveen area of Bessbrook, Co Armagh, just before midnight.
There were no reports of any injuries.
A spokesman for the PSNI said Army technical experts had been called to the scene.
It is understood the pipe bomb was thrown at a van parked outside a house in Ardaveen Park and caused minor damage to the vehicle.
A forensic examination has been carried out.
The attack is not believed to be terrorist-related.
A PSNI spokesman said detectives were working to establish a motive and appealed for anyone with information to come forward.
SDLP MLA Dominic Bradley said it was fortunate no-one was injured.
“I condemn those responsible for the detonation of this pipe bomb at Ardaveen, a quiet residential area, last night. In doing this they have shown scant disregard for life and, had the circumstances been different, someone could have been killed or seriously injured by this device.
“I don’t know what these people hope to achieve. The use of violence is wrong regardless of the context.”
