25 British MPs Have Been Sent Death Threats Via Email

London's Metropolitan Police Service (MPS) are investigating a string of death threats made towards at least 25 MPs who have been singled out over email.

"The [MPS] are investigating a linked series of threatening emails which have been received by a number of MPs since Friday, August 26. All of these emails have been received via MPs parliamentary accounts," a Metropolitan Police statement said.

"No arrests have been made. Enquiries are ongoing. This is not being treated as a terrorist incident," the statement added.

A photograph of a decapitated man along with the words: "Warning, I am going to kill you and kill all of your family," has been sent to 25 MPs from various parties. Former Labour frontbencher Chris Bryant revealed the details to the British press, saying he had received "five or six" similar messages already this year.

​"In the last year there has been a slew of these, I've received five or six so far this year. It is difficult to know how seriously to take them, but when they mention your family, you have to take them seriously." 

Concern for MPs safety has increased following the tragic death of Labour MP Jo Cox, who died in hospital after being shot three times and repeatedly stabbed in Birstall, West Yorkshire, where she was due to hold her constituency surgery. A 52-year-old man has been charged with her murder.

A report into MPs' security recently found that four out of five had been victims of abuse or aggressive behavior. 130 MPs have also demanded an overhaul of their personal security including a locks change, panic alarms and more CCTV.

Earlier this month, Jess Phillips, Labour MP for Yardley in Birmingham admitted she was installing a panic room in her constituency office following threats to her personal safety.

Chris Bryant told LBC Radio in London that he blamed the Internet for the rise in online attacks towards MPs.

A well-known critic of Labour leader Jeremy Corbyn, Mr. Bryant also said he'd never known the Labour party to be in such an "unpleasant state," with members attacking other Labour party members online every day and demonstrations erupting outside MPs' officers.

"I think Jeremy has been very very slow to act on that," he said.
