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, 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.
