Putzgruppe (Cleaning Squad) was a German left-wing militant group, that emerged from the German student movement and was active in the 1970s. It participated in riots against the police in Frankfurt.
According to Daniel Cohn-Bendit, they tried "to use helmets, to protect themselves against the state power, which sought trouble". The group was the militant branch of a left-wing political organisation called "Revolutionärer Kampf" (Revolutionary Fight). The future German foreign minister Joschka Fischer was known to be the head of this group. The term Putzgruppe became popular in Germany in 2000, when the trial against Hans-Joachim Klein, a former member of the group, begun. He joined the terrorist Revolutionary Cells in 1974.
The groups usual area of operation was the violent defense of occupied buildings against eviction by the police. In 2001 Joschka Fischer gave an interview to the German magazine Stern, in which he said that they threw stones.

Hans-Joachim Klein was part of the group and said, he and other comrades had exercised confrontations with the police in role plays in the Frankfurt city forest.
