German police detain 52 in biker brawl

German police said Sunday they used dogs and truncheons to break up violent clashes between the Hells Angels and a rival biker gang in the northern city of Bremen and detained 52 suspects. Officers moved in late Saturday when members of the Mongols gang descended on the local clubhouse of the Hells Angels. "Members of the two clubs began provoking each other and it eventually led to injuries" police said in a statement. A group of Mongols and their supporters that had been led away later began resisting police. "In response officers deployed dogs and truncheons" the statement said. A total of 52 people were taken into custody while one officer and two civilians were injured. Many biker gangs in Germany have links to organised crime leading to rampant violence between warring groups.
