After three nights Police calm London Riots

On Aug-4 Police investigating gun crime in the black community shoot 29-year-old Mark Duggan after stopping him in a taxi in Tottenham, north London. He dies at the scene after the shooting. Britain's police watchdog opens an inquiry into the fatal shooting.

Rioters have looted shops, set fire to buildings and clashed with police in three nights of disorder in London.

Now London remained largely quiet with a heavy police presence on the streets but unrest spread across central and northern England on a fourth night of violence that has blighted the David Cameron government's image and ability to hold the 2012 London Olympics safely.

With 16,000 police officers deployed in London, the streets remained calm after three previous nights of rioting.

But there was unrest in Manchester, Salford, Liverpool, Wolverhampton, Nottingham, Leicester and Birmingham with shops being looted and set alight.

So far 768 people have been arrested and 105 charged in connection with violence in the capital.

British Prime Minister David Cameron said he would recall parliament from its summer recess for a day on Thursday after rioting swept through London for three consecutive nights.

Talking tough, the Prime Minister, who rushed home after cutting short his vacation in Italy, said the culprits will be brought to bear the consequences of their actions and the government was determined to see that justice is delivered to the law abiding citizens.

Deputy Assistant Commissioner Stephen Kavanagh said, never before fired to deal with riots in England - would be "considered carefully" in the event of further disorder. Sporadic violence has broken out in several cities around England last night.
