During the night, several garbage cans and car tires burned on streets in Berlin-Kreuzberg.
People were not injured, the police said on Thursday.
Accordingly, strangers had set the fire on Bethaniendamm, Engeldamm and Köpenicker Strasse.
Whether there is a connection with the planned evacuation of the left-wing autonomous car camp "Köpi" by the police on Köpenicker Strasse in Berlin-Friedrichshain on Friday is being examined by the state security service.
Berlin - In protest against the eviction, strangers damaged the glazing of the entrance doors on Wednesday morning at the Bürgeramt in Berlin-Mitte.
On Tuesday night, tires had burned on Rigaer Strasse.
The camp is considered to be one of the last symbolic projects of the left-wing radical scene in Berlin.
In June, the district court ordered the evacuation of the property with inhabited construction vehicles.
