According to the police, there was a fight with 20 to 30 people in Mainz on Tuesday evening.
The group was said to have "not just met by chance" in the area of the Kaiser-Wilhelm-Ring, the officials said.
Some of the suspects used telescopic batons.
When the police arrived, everyone involved had already fled.
Wallet and cell phone lost at the crime scene
The emergency services were still able to identify two suspected thugs: One had lost his wallet at the scene of the confrontation and returned to the scene while the police were still present.
A witness recognized him.
A second man lost his cell phone in the conflict and the police had seized it.
The background of the brawl and the exact number of those involved is still unclear, according to the police.
