Mass train stabbings linked with attack on boy, 14

The suspected attempted murder of 10 people on a train in Cambridgeshire is being linked with three more knife incidents, police have confirmed.

Anthony Williams, 32, of no fixed abode, has been charged over the mass stabbing which took place on the Doncaster to London King's Cross service on Saturday.

British Transport Police (BTP), which has taken the lead on the inquiry, said it was being linked with the stabbing of a 14-year-old boy in Peterborough on Friday evening.

Two incidents in which a man entered a barber shop in the city - on at least one occasion holding a knife - were also being linked.

BTP said it was also linking the stabbings on the rail service, which made an emergency stop in Huntingdon, with a fourth incident on a DLR train at Pontoon Dock in the early hours of Saturday.

Mr Williams has already been charged with an 11th count of attempted murder, after a 17-year-old person was stabbed on the train in east London.

Dep Ch Con Stuart Cundy said BTP was increasing visibility of police officers across the railway network to "reassure" both staff and the "travelling public".
