A series of parcel bombs sent to locations in London and Glasgow earlier this year have been connected to devices targeting army offices in 2014.
Anti-terror investigators have said they are now “formally linking” the incendiary devices posted in March and explosives sent to military recruitment centres five years ago.
A main line of inquiry is that the latest packages were sent by “a violent dissident republican group”, according to Scotland Yard.
At the time, a group claiming to be the New IRA said it was responsible for the bombs sent to Waterloo railway station and offices at Heathrow and London City airports.
