British Prime Minister David Cameron will meet with his crisis-response committee again Wednesday after a fourth night of violence hit London neighborhoods and spread elsewhere in the country.
London's Metropolitan Police Service has arrested 768 people in connection with violence, disorder and looting, the department reported early Wednesday.
Authorities have charged 167 people with crimes, according to CNN Internationa.
Thousands more police officers flooded London streets Tuesday in a bid to end Britain's worst rioting in a generation as nervous shopkeepers closed early and some residents stood guard to protect their neighborhoods. Unrest spread across central and northern England on a fourth night of violence driven by poor, diverse and brazen crowds of young people.
Scenes of ransacked stores, torched cars and blackened buildings frightened and outraged Britons just a year before London is to host the summer Olympic Games, and brought demands for a tougher response from law enforcement.
London's Metropolitan Police put thousands more officers in the streets and said that by today there would be 16,000 - almost triple the number present Monday, reports San Francisco Chronicle.
Some officials, including former London Mayor Ken Livingstone, a leftist commonly known as "Red Ken," blamed the unrest on recent government budget cuts, which have hit education, social assistance and community budgets.
But to many Britons, the riots were a near-anarchic crime spree that had nothing to do with politics, with hooded youths breaking into stores to help themselves to plasma TVs, clothes and even cash, says Los Angeles Times.
