|The police operation was in the Ostheim district of the city. Police used specially modified vehicle, called the Patriot 3. The vehicle broke down the doors to the clubhouse, allowing police to storm into the building. During the raid, police discovered and seized weapons, including knives and a gun, and cash. Around 100 officers were involved.|
| The reason for the raid was a dispute between the Hells Angels and the Bandidos. The rival gang was celebrating the birthday of their president, Aykut Ö, when 40 Hells Angels tried attacking the celebrations in Cologne’s city centre.|
They reportedly tried to get into the nightclub where the celebrations were taking place, but were stopped at the entrance by officers with pepper spray and batons. Hells Angels claim that the area where the nightclub lies belongs to them. They apparently saw the party, where about 100 people were invited, as a provocation.
