London was crying on pain from 6th of August to 11th of August.
Between 6 and 10 August 2011, many London districts and some other cities and towns in England suffered widespread rioting, looting and arson.
Following a peaceful march on 6 August 2011 in relation to the police response to the fatal shooting of Mark Duggan by Metropolitan Police Service firearms officers on 4 August 2011, a riot began in Tottenham,North London. In the following days, rioting spread to several London boroughs and districts and eventually to some other areas of England, with the most severe disturbances outside of London occurring in Bristol and cities in the Midlands and North West of England. Localised events connected to the major riots also took place in many smaller towns and cities in England.
The riots were characterised by rampant looting and arson attacks of unprecedented levels. As a result,British Prime Minister David Cameron returned early from his holiday in Italy and other government andopposition leaders also ended their holidays to attend to the matter. Additionally, all police leave was cancelled and Parliament was recalled on 11 August to debate the situation.
As of 15 August, about 3,100 people have been arrested, of whom more than 1,000 have been charged. Source here
