Police evacuated buildings at two British universities on Wednesday after receiving reports of suspicious packages, a day after parcel bombs were sent to two airports and London's busiest train station.
Police in eastern England said they had put a cordon in place at the University of Essex and evacuated some buildings after receiving a call about a suspect package. The bomb squad had been called in.
In Scotland, the University of Glasgow also said several buildings had been shut and classes cancelled after a suspicious package was found in the mailroom.
Police had advised the buildings should be closed for the rest of the day but no further information was available on the nature of the package.
Police blow up device sent to University of Glasgow
Scottish police said they had carried out a controlled explosion on a device sent to the University of Glasgow and were liaising with officers in London where parcel bombs were sent to major transport hubs.
"The package was not opened and no one was injured," Assistant Chief Constable Steve Johnson said. "The emergency services were alerted and several buildings within the estate were evacuated as a precaution. A controlled explosion of the device was carried out this afternoon."
Three small parcel bombs were sent to two airports and London's busiest train station on Tuesday. "It is too early to say whether there is a link," Johnson said.
The two varsities were the University of Essex and the University of Glasgow.
