Officers investigating a suspicious package sent to the University of Glasgow have now linked the incident with a similar investigation being carried out by the Metropolitan Police. 

Police had earlier said they were working with their colleagues south of the border but have now said there were similarities in the packages and that the incidents are thought to be linked. 

Three small improvised explosive devices sent to addresses in London on Tuesday before the Glasgow package was found at the university's mailroom on Wednesday.

Inquiries have established that a package received at the Royal Bank of Scotland building on Glasgow Road Edinburgh today posed no risk to the public and contained promotional goods.

Police Scotland Counter Terrorist officers are carrying out an investigation into the device sent to the University of Glasgow, but officers from both investigation teams are now working together closely to share any information or intelligence that could assist their respective inquiries.

Assistant Chief Constable Steve Johnson of Police Scotland, said: "The package sent to the university was not opened and no one was injured. A controlled explosion of the device was carried out this afternoon by EOD.

"There are similarities in the package, its markings and the type of device that was recovered in Glasgow to those in London. Therefore, we are now treating it as being linked to the three packages being investigated by the Met in London and both investigations are being run in tandem.

"Our enquiries into the Glasgow package are at an early stage but there is no ongoing risk to the public.

“The package in Glasgow was identified by alert staff at the university mailroom who had received protective security information advising them to be vigilant and to report suspicious packages.

"The same advice has already been sent to a range of businesses, including transport hubs and mail sorting companies, and will now also be sent to those in the education sector.

"Anyone who sees something suspicious should report it to the police immediately.”
