London Hit By Riots After Police Shooting

Groups of masked and hooded young people looted shops, attacked police officers and set fire to vehicles in weekend violence in London that has raised questions about security ahead of the 2012 Olympics and revealed pent-up anger against the city's police. The violence broke out in the gritty north London suburb of Tottenham on Saturday night amid community anger over a fatal police shooting of a 29-year-old father of four.

Police said "copycat criminal" violence spread to other parts of the city Sunday night and early Monday, including, briefly, London's main shopping and tourist district at Oxford Circus. The protest over the death of Mark Duggan, who was gunned down in disputed circumstances Thursday, was initially peaceful. But it turned ugly after between 300 and 500 people gathered around Tottenham's police station late Saturday. The BBC's Nicola Stanbridge reports.
