London, Aug 9 (IANS) London looters struck at a fancy dress store from where they stole masks so that they could hide their identity, media reports said.

At Clapham Junction, the looters took away masks to conceal their identity, reported BBC.

The Telegraph said that up to 1,000 youths attacked Clapham Junction in south London, where they ransacked stores.

TV footage showed hundreds of masked looters running through the streets.

Rioters have paralysed London for the past three days.

London, which is to stage next year's Olympic Games, witnessed a third night of violence as other cities saw unrest. Protesters were seen destroying and looting shops, setting cars and buildings alight and engaging in clashes with police.

Violence began in the British capital's northern district of Tottenham Saturday over the fatal shooting of a man by police.

Some 300 people gathered outside a police station in Tottenham Saturday night to demand "justice" after 29-year-old cab driver and alleged drug dealer Mark Duggan was killed in Thursday's shootout with police.
