On 15 January 1978, a fire in Barcelona's Scala nightclub killed four people. The ensuing trial became known as the Scala case. Initially, some of the protestors were condemned to prison sentences, but after some years, it was revealed that the cause of the incident were the actions of an infiltrated police officer, who was finally condemned.
