A 32-year-old man is in custody after a violent stabbing spree aboard a London-bound train Saturday night left 10 people injured—two critically—before armed police subdued him with a Taser at Huntingdon station.

Authorities have charged the suspect with attempted murder and confirmed the incident is being treated as isolated, not terror-related.

The attack occurred on the 6:25 p.m. LNER service from Doncaster to King’s Cross, shortly after the train departed Peterborough at 7:29 p.m. Within minutes, passengers reported screams and chaos as the suspect moved through carriages, stabbing multiple victims. One witness described seeing a man collapse, shouting, “They’ve got a knife, I’ve been stabbed,” while others hid in toilets or were trampled in the panic.

The train made an emergency stop at Huntingdon by 7:44 p.m., where more than 30 armed officers responded rapidly, aided by the station’s proximity to Cambridgeshire Police Headquarters. Dramatic footage captured the suspect—dressed in black and wielding a large knife—fleeing the platform before being Tasered and restrained by police. Officers were heard shouting commands as they tackled him, with police dogs assisting in the arrest.

British Transport Police Superintendent John Loveless confirmed two arrests were made at the scene. However, the second suspect, aged 35, was released without charge on Sunday. The 32-year-old remains in custody and faces multiple counts of attempted murder.

Of the 10 victims, nine sustained life-threatening injuries, primarily to the head and neck. Two remain in critical condition, while four have been discharged. The East of England Ambulance Service deployed a large-scale response, including air ambulances, to transport victims to Addenbrooke’s Hospital.

The incident initially triggered a “Plato” alert—a protocol for suspected mass casualty attacks—but this was later rescinded. Defence Secretary John Healey described the event as an “isolated attack,” while Prime Minister Keir Starmer called it “appalling” and praised emergency responders. Huntingdon MP Ben Obese-Jecty commended the swift turnout of police and medical teams.

Witnesses recounted the horror. Viorel, a taxi driver who filmed the arrest, said the suspect shouted “kill me” repeatedly after being subdued. Another passenger, Olly Foster, told the BBC he initially thought the incident was a Halloween prank until he saw blood on his hands.

LNER issued a “Do Not Travel” advisory and arranged coach transport for stranded passengers. The attack has renewed calls for improved rail security amid rising knife crime across the UK. British Transport Police are urging witnesses to come forward, referencing incident number 495.
