11 people were injured in the attack. The train crew member who tried to stop the suspects is in a life-threatening condition, police said.
A 32-year-old British man was the sole suspect accused of a mass stabbing on a train in England, after another man arrested in the case was released on Sunday with no charges.
British police said the knife attack that put 11 people in hospital was not a terrorist incident. A 35-year-old man who had been arrested earlier was released after officers concluded he was not involved in the attack.
