Extra police officers have been deployed across England's railway network after a stabbing attack on a Doncaster-London train left 11 people injured. Two British men in their thirties were arrested on suspicion of attempted murder, with two victims still in life-threatening condition. The incident has caused major disruption on services linking the east of England with London.

A “surge” in police presence is expected until at least Tuesday, focusing on major stations including London, Birmingham, York, Leeds and Manchester, as well as Huntingdon. Officers will also travel on East Coast Main Line trains, shifting from their usual station-based duties to help “reassure passengers”.

Investigators have not yet identified a motive, but British Transport Police said there was currently “nothing to suggest” the attack was terror-related. Huntingdon station remained cordoned off on Sunday, with the affected London-bound train still at the platform as enquiries continued.

Rail operators have warned of continued disruption, with delays and cancellations across Great Northern, LNER and Thameslink routes. Affected destinations include London Kings Cross, Peterborough, Lincoln, Doncaster, Leeds, Bradford Forster Square, Harrogate, Welwyn Garden City and Hitchin.
