British police released one of the suspects in a knife attack on a train in Cambridgeshire on Sunday, confirming that five victims have now left the hospital while one remains in critical condition. Counter-terrorism police assisted in the initial investigation of the random stabbing incident on a train traveling to London in eastern England on Saturday. John Lovell of British Transport Police told the media on Sunday that at this stage there are no indications of a terrorist motive. Earlier, police had stated that the knife attack on a train in Cambridgeshire, which injured 11 people, was not terrorism-related, adding that they had arrested two British men, one of whom was later released without charge.
