Counter-terrorism officers have joined the investigation into a mass stabbing that occurred on a train, leaving nine people critically injured.
The incident took place on Saturday evening when police were called around 7:40 p.m. to Huntingdon station in Cambridgeshire, where the train was halted.
According to reports, a man armed with a large knife went on a violent rampage on the high-speed train shortly after it departed from Peterborough. Police are believed to have subdued him with a Taser.
British Transport Police confirmed that two suspects have been arrested and ten individuals were taken to hospital, with nine suffering life-threatening injuries.
Armed officers, paramedics, air ambulances, and transport police all responded to the emergency. The train was traveling between Doncaster and London King’s Cross.
Witnesses told Sky News that the attack began about 10 minutes after leaving Peterborough, prompting passengers to activate the emergency alarm. Some passengers were reportedly trampled in the chaos, while others hid in toilets to escape. One witness said he saw an attacker being Tasered by police before being detained.
Authorities declared the situation a “major incident.” At one point, the emergency services activated the “Plato” protocol — a national code for a suspected terror attack — but later withdrew it.
Prime Minister Sir Keir Starmer called the attack “appalling” and “deeply concerning,” expressing sympathy for the victims and gratitude to first responders.
Huntingdon MP Ben Obese-Jecty and Home Secretary Shabana Mahmood both voiced their sorrow, with Mahmood urging the public not to speculate while the investigation continues.
Speaking from the scene, Obese-Jecty told Sky News he had “never seen such a large-scale emergency response.”
Shadow Home Secretary Chris Philp condemned the “brutal mass attack by two perpetrators,” while Tory Party chairman Kevin Hollinrake described the scenes as “horrifying,” both praising the emergency services for their efforts.
