Police believe a suspicious package found at the University of Glasgow is linked to explosive devices sent to three London transport hubs on Tuesday. A controlled explosion was carried out on the suspicious package, which was found at the university’s mail room on Wednesday morning. Assistant Chief Constable Steve Johnson, of Police Scotland, said the package had not been opened and there were no injuries to university staff or students. On Tuesday, explosive devices were discovered at Waterloo Station and buildings near Heathrow and London City airports. The devices were small and, while one package was opened, there were no injuries.
