Some 800 police officers were involved in the raids that began early Wednesday morning in eleven cities in the western state of North Rhine-Westphalia, with a focus on Cologne and the Ruhr Valley region, Essen police said.
The authorities targeted the premises of 34 suspects belonging to the Al-Salam-313 gang. They primarily searched for evidence regarding their criminal activities, police spokeswoman Sylvia Czapiewski said.
Police detained one suspect and seized computers, storage devices, drugs, cash and counterfeit money. "According to current knowledge, this was a successful strike against organized crime," Herbert Reul, the interior minister of the western state told reporters, adding that the raids had been prepared for months.
