For five nights in 2011, cities in the UK saw pockets of violence after the killing of Mark Duggan, a 29-year-old man from Tottenham in north London, who was shot dead by police.

The shooting was a catalyst that sparked riots around London, and then in cities across the UK.

Five people ended up dead and more than £200m of damage was done to businesses and property.
