As the 25th anniversary of the Brixton riot approaches, BBC News examines the significance of the events of April 1981.

The rioting which began in Brixton, in the south London borough of Lambeth, in April 1981 shocked the nation.

For three days, rioters - predominately young, black men - fought police, attacked buildings and set fire to vehicles.

More than 300 people were injured and the damage caused came to an estimated value of £7.5m.

What was most shocking to many people was the unexpectedness of events. On the surface it seemed that black people were well-integrated into the fabric of UK society.
