British riot policemen stand in front of a burning building in Croydon, South London on August 8, 2011. Now in it's third night of unrest, London has seen sporadic outbreaks of looting and clashes both north and south of the river Thames. Numerous buildings were set on fire in Croydon including a 140 year old furniture store as hundreds of looters plundered high street shops of their goods.
