The Garda Commissioner, Noel Conroy, has said no link has been established between last night's pipe bomb attack and another bomb that exploded near in Coolock two days ago.
The Garda Technical Bureau has spent the day examining the scene of last night's explosion in the driveway of a house.
The device was placed under a car parked in the driveway of a house on Roseglen Avenue in Kilbarrack exploded.
The spare wheel of the Renault Clio bore the brunt of the explosion, which seriously damaged the car and also blew in the front window on the ground floor of the house.
A number of people were in the house at the time. They suffered shock but no other injuries.
It is understood the device is likely to have had a timing mechanism.
The army bomb disposal unit was called to the scene and the area was sealed off.
