Overview
- British Transport Police said the sole suspect, a 32-year-old UK-born man who boarded at Peterborough, remains in custody and a second man initially detained, 35, has been released with no involvement.
- The Doncaster–London King’s Cross service was halted at Huntingdon after an onboard alarm, where armed officers intervened and used a Taser to subdue the knife-wielding attacker.
- Ten people were taken to hospital, five have since been discharged, and one person—an LNER staff member who tried to stop the assailant—remains in a critical condition, according to BTP.
- The incident was declared a major incident and a large knife was recovered, with the national ‘Plato’ protocol initially activated and later lifted as the situation was brought under control.
- LNER warned of major disruption across its route during the response, and police maintained an enhanced presence at stations as urgent forensic and witness inquiries continued.
