UK police arrested two suspects after a mass stabbing on a London-bound train late Saturday that left 10 people in hospital, nine likely with "life-threatening injuries".

Two men born in Britain are suspected of carrying out the Huntingdon train knife attack which is not believed to have been motivated by terrorism, police have said.

Colin Hardy, who lives in Huntingdon and attends All Saints' Church, said he had not "come to terms" with the incident as "it is not the sort of thing that happens around here".
