Since February 2026, the Rendsburg criminal police had investigated a 34-year-old German man for narcotics offences, suspecting him of dealing in various drugs.[1] Covert investigations identified six further German suspects aged between 21 and 45.[1] The six were suspected of having sold or stored drugs or otherwise having been involved in the trade.[1]

On the morning of 10 November 2026, police officers executed seven search warrants.[1] The criminal police forces from Rendsburg, Schleswig and Eckernförde took part, along with several police dog handlers and riot police from Eutin.[1] Officers seized several kilograms of cannabis, several hundred grams of cocaine and several grams of amphetamine.[1] They also confiscated two high-value vehicles as means used in the offences.[1]

Six suspects were released after the police measures because there were no grounds for detention.[1] Police initially took the suspected principal offender into custody.[1] On 11 November 2026, at the request of the Kiel public prosecutor’s office, the 34-year-old was brought before a judge who issued an arrest warrant, and the man was then taken to Neumünster prison.[1]
