A machete-wielding man was Tasered on a railway station platform as “terrified” rush hour commuters looked on.

Police pinned the man – filmed waving a “massive” blade at Tulse Hill station in South London – to the ground shortly after 18:30 GMT on Monday. Witnesses described “chaos” as he chased people with the weapon.

A 59-year-old man arrested on suspicion of attempted murder and possessing an offensive weapon has since been sectioned under the Mental Health Act. The suspect, from Croydon, was sectioned after being assessed by medics, British Transport Police (BTP) said.

Asst Ch Con Robin Smith, from BTP, added: “This would have been a particularly frightening incident for those passengers at the station or on board trains a Tulse Hill station. “I am especially grateful to our Metropolitan Police colleagues who did a great job in detaining this man.”
