Metropolitan Police

A masked mob pelted police with missiles as they attended the scene of a stabbing.

The "volatile" crowd of around 30 people covered their faces and threw bottles at officers during the incident in Hackney last night.

Police were called to Chatsworth Road at around 11.30pm after an 18-year-old man suffered stab wounds to his upper body.

No officers were injured during the trouble, while one pursued and apprehended a suspect "despite continuing threats from a volatile crowd", a Metropolitan Police spokesperson said.

Some 11 people "will be interviewed as witnesses" by the police searching for missing Madeleine McCann, Good Morning Britain heard.

British and Portuguese "men and women" are expected to be quizzed by the police over what happened to the missing youngster.

Four men arrested in connection with an alleged Islamist terror plot just two days before Remembrance Sunday will be held for a further seven days.

Counter-terror police detained the men, aged 19 to 27, on Thursday night at locations across west London and High Wycombe in the Thames Valley area, Scotland Yard said.
