A device found in the Crumlin area of Dublin last night has been declared a hoax.
Gardaí and the Army Bomb Disposal Team attended the scene on Kildare Road after 9pm last night.
The area was sealed off and people were evacuated from their homes when a cylinder type device was found beside a car.
The device contained nails, screws and a powdered substance but no explosives.
It was declared a hoax by the bomb disposal team and residents were allowed return to their homes after 11pm.
24 hours earlier a pipe bomb exploded in the front garden of a house in nearby Monasterboice Road.
It is believed the device was thrown from a passing car; no-one was injured.
Anyone with information is asked to contact Sundrive Road Garda Station on 01 6666600, or the Garda Confidential Line on 1800 666 111.
