Police have condemned a wave of "copycat criminal activity" across London in a second night of looting and disorder following riots in Tottenham.
More than 100 people have been arrested as officers were attacked, police vehicles damaged and shops looted.
Disorder spread to Enfield, Walthamstow and Waltham Forest in north London and to Brixton in the south of the city.
Home Secretary Teresa May has cut short her holiday to return to the UK following the disorder.
Some 35 officers have been injured over the two nights of rioting.
Three officers were hurt when a vehicle hit them as they tried to make an arrest in Waltham Forest, east London.
Clashes broke out in Enfield, north London, on Sunday evening where shop windows were smashed and a police car damaged.
