Ben Johnson stripped of Olympic gold in Seoul 1988

On 27 September 1988, Ben Johnson was stripped of his Olympic 100m gold medal after testing positive for anabolic steroids.

The Canadian sprinter had won the race in a new world record of 9.79 seconds but he was sent home from the Seoul Olympics in disgrace.

American Carl Lewis was promoted to gold, with Britain's Linford Christie taking silver and bronze going to another Calvin Smith of the United States.
