- Muhaydin Mire, 29, of east London, is charged with attempted murder
- "The threat from terrorism remains at severe," a police official says
- One person suffered serious injuries, but they're not considered life-threatening
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.
Authorities later said that the suspect, Muhaydin Mire, of east London, had been charged with attempted murder. He's expected to appear in court on Monday.
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.
One man, 56, suffered serious knife injuries in the attack and was taken to an east London hospital, where he remains in a stable condition. His injuries are not considered life-threatening, police said.
