The stabbing of a 14-year-old boy and two reports of a knifeman seen at a barbers in Peterborough are being investigated as part of the police probe into a mass stabbing on a high speed train.
Cambridgeshire police said that the teenager was non-fatally injured at 7.10pm on Friday, before a man with a knife was seen at a barbers in Fletton 15 minutes later, although this was only reported to police two hours later.
