Police out in force in Tottenham

Police are on the streets of Tottenham, north London, where overnight riots saw petrol bombs thrown at officers and patrol cars and buildings set alight.

Eight injured police officers were taken in hospital, at least one of them with head injuries.

The unrest began after a protest over the fatal shooting by police of 29-year-old Mark Duggan on Thursday.

About 300 people gathered outside the police station on the High Road after demonstrators demanded "justice".

London Ambulance Service said a total of 10 people had been treated and nine had been taken to hospital.
