Police investigating parcel bombs sent to Celtic manager Neil Lennon and two high-profile supporters of the club on Tuesday said another suspect package had been intercepted in Northern Ireland.
Officers are still looking for whoever was responsible for sending parcel bombs to Lennon and the two high-profile supporters. The packages were designed to cause serious harm to the recipient, police said.
The latest package - believed to be a parcel bomb - was found at the National Return Letter Centre in Belfast, where mail which has not been delivered and has no return to sender address is retained by Royal Mail. It is the fifth package to be intercepted.
Strathclyde Police believe the package originally entered the postal system at around the same time as the devices that are already under investigation.
Officers from the Police Service of Northern Ireland recovered the package and alerted the Scotland force. A spokeswoman for Strathclyde Police said the latest find would be made safe and handed over to officers in Scotland for further investigation.
It is understood the latest package was not addressed to a particular individual.
