Police have released photographs of the Brexit day bomb they believe the Continuity IRA (CIRA) was responsible for.
A bomb was found attached to a lorry in Lurgan, County Armagh, on Tuesday morning.
It is thought the device may have been intended for a Brexit day attack.
Police said they first received a report about an explosive device in a lorry at Belfast docks on 31 January - the date the UK left the EU.
It was claimed the lorry was due to travel by ferry to Scotland.
