Northern Ireland Police received reports of an explosive device on a lorry in Belfast docks last Friday. The lorry was scheduled to travel to Scotland but as no device was found, the lorry continued as planned and arrived in Scotland. Following a search, no device was found.
On Monday, police officers were given a second report of an explosive being attached to a vehicle which was found after a two-day search.
Following a search of 400 vehicles, an explosive device was found attached to a vehicle in the Silverwood Industrial Estate in Armagh.
The device was made safe by ammunition technical offciers.
Northern Ireland's terrorism investigation unit release a statement today asking for any witnesses to come forward.
Brexit Day: Dissident Republican plot to blow up lorry foiled
Detective superintendent, Sean Wright said: "It is clear from the information available to police that dissident republicans deliberately and recklessly attached an explosive device to a heavy goods vehicle in the full knowledge and expectation that it would put the driver of that vehicle, road users and the wider public at serious risk of injury and possible death.
"Had this vehicle travelled and the device had exploded at any point along the M1, across the Westlink or into the harbour estate, the risks posed do not bear thinking about.
"The only conclusion that we can draw is that once again dissident republicans have shown a total disregard for the community, for businesses and for wider society."
Northern Ireland police have asked for any witnesses of suspicious activity on the estate between 4-10pm on Friday, January 31 to come forward.
