Police control of a 24-year-old man in Frankfurt's Bahnhofsviertel got out of hand.
Officials had approached him because, according to their assessment, he was investigating the illegal street prostitution.
As the police further announced on Sunday, the angry man from the Rheingau-Taunus district then stood up in front of an officer and screamed loudly.
Frankfurt - Only with the support of another patrol could he be overpowered.
He kicked an officer in the stomach and bit a policeman.
Both should have broken off the service.
"The resistance could only be broken through targeted strikes and the use of pepper spray," the police said.
During the arrest on Saturday morning, around 50 people observed the operation, many of whom filmed the situation.
The suspected man was later released by the police.
According to the police, it was initially unclear whether the suspicion of illegal street prostitution was confirmed.
