Brixton riots: Archive
The riots which broke out in Brixton, south London in 1981 were the first serious riots of the 20th century that the Metropolitan Police dealt with.
On 10 April, a policeman tried to assist a young black man who turned out to have been stabbed.
A crowd of local people gathered, bricks and bottles were hurled at the policeman, and at further police cars which arrived to assist.
This began a weekend of violence and destruction, directed mainly at the police, with whom many were unhappy as a result of their stop and search policies in the area.
This BBC archive footage shows the aftermath of the first day of rioting.
