The Death Daggers were a Turkish-German biker gang which was founded by Ugur Kubilay. The Death Daggers were considered by the Berlin Police to be a left-wing gang, and the Death Daggers were rivals with the neo-Nazi Marzahn Brotherhood. In 2018, the gang came to Berlin to attend the funeral of the murdered footballer Orkan Erdem and offered their services to his grieving brother Pusat Erdem, who believed that the neo-Nazis of Marzahn were responsible for his brother's death. As a result, the Death Daggers attacked the Marzahn Brotherhood in a 200-man brawl, resulting in several injuries and the death of Marzahn leader Johann Henkenmaier.
