British police said one of two men arrested over a stabbing attack on a London-bound train has been released without charge.
The only remaining suspect is a 32-year-old British man who remains in custody on suspicion of attempted murder.
Police said earlier that two men, aged 32 and 35, were arrested after the attack that left 11 people hospitalized. One victim remains in a life-threatening condition, a member of train staff whom police say saved lives with his "heroic" actions.
Police have dismissed speculation that the attack was terrorism-related and said two victims remain in a life-threatening condition.
The suspects, a 32-year-old Black British man and a 35-year-old man of Caribbean descent, were arrested eight minutes after the first emergency calls were made at 7:42 p.m. from aboard the train, where passengers had reported scenes of panic and chaos with many running through the carriages and some seeking safety in the toilets.
