Overview
- Two people were initially detained at Huntingdon, but a 35-year-old man was released after checks as investigators focused on a single British suspect who boarded at Peterborough.
- Ten people were taken to hospital; by Sunday five had been discharged and an LNER staff member who tried to intervene remained in critical condition.
- Counter-terrorism officers are supporting the investigation, which authorities stress does not presently indicate a terrorism link.
- Armed officers stopped the Doncaster–King’s Cross service at Huntingdon and used a Taser to subdue a knife-wielding suspect, and police recovered a blade at the scene.
- Forensic work and witness interviews are ongoing as LNER reports service disruption and officials commend the actions of passengers and staff.
