The force tasked with making sure transport links are policed has announced it will draft in armed officers to patrol trains.

The British Transport Police (BTP) made the decision to call in reinforcements after the Prime Minister raised the terror threat level following Monday's terror attack in Manchester.

The specialist officers will be posted on trains around the country as part of a nationwide step up in security operations.

It is the first time any armed officers have been put on duty to cover transport links, according to a statement by the BTP.

Chief Constable Paul Crowther from British Transport Police, said: "Since the devastating events in Manchester on Monday evening, our force has radically increased the presence of our officers nationwide.

"It is important to note that we do not have any specific intelligence in relation to train services but are taking this action to ensure we can protect and reassure the public" - Paul Crowther

"By having firearms officers on board trains we’re ensuring that trains remain as safe as possible for passengers.

"Our patrols will be highly visible and passengers should feel comforted by their presence.

"Please do speak to them if you have any concerns at all.

“This is part of our national mobilisation plan to deal with the current and ongoing threat.

"It is important to note that we do not have any specific intelligence in relation to train services but are taking this action to ensure we can protect and reassure the public."
