LONDON — A man has been charged with 10 counts of attempted murder following a mass stabbing on a train in the U.K.

Anthony Williams, 32, from the city of Peterborough in eastern England, was arrested on a train at Huntingdon station on Saturday night after multiple people were stabbed, the British Transport Police said.

Williams was charged with ten counts of attempted murder, one count of actual bodily harm and one count of possession of bladed article, the BTP said in a statement released on Monday.

Williams was also charged with another count of attempted murder and possession of a bladed article in connection to an incident at Pontoon Dock tube station in east London on Nov. 1, the statement said.

Speaking at the scene of the Huntingdon attack on Sunday morning, BTP Superintendent John Loveless said the suspect was arrested within eight minutes of the first emergency call being received.

A second man was also arrested at the scene but was later released after investigators determined he was not involved, police said.

“At this stage, there is nothing to suggest this is a terrorist incident,” Loveless said. “At this early stage, it would not be appropriate to speculate on the causes of the incident.”

A total of 11 people were treated at hospital for injuries related to the stabbing, Loveless said. Of those, two 11 victims remained in critical condition as of Sunday morning, he added.

British Prime Minister Keir Starmer said Saturday’s attack was an “appalling incident” that was “deeply concerning.”
