British police say they are investigating an unprovoked knife attack in an east London Tube station Saturday, which left a man with serious injuries, as a terrorist incident.
The assailant, 29, was subdued with a stun gun and arrested on suspicion of attempted murder at 7:14 p.m. Saturday in the suburb of Leytonstone, London’s Metropolitan Police said.
Police had been dispatched to the station after receiving emergency calls reporting that a man had stabbed people and was threatening others, police said. The man threatened officers as they tried to reason with him, a statement said.
Police are looking into reports that the suspect yelled, “This is for Syria,” during the attack, said Chioma Dijeh, a spokeswoman for the Metropolitan Police.
