German police detained a suspected leader of a criminal network believed to be operating in Sweden in Berlin, authorities said. The man, around 30 years old, was held after an international operation involving police from Germany, Romania and Sweden, with support from Europol. Swedish police said he had been temporarily staying in Germany. Swedish police described the case as part of an extensive operation with long-term surveillance and monitoring measures. Investigators linked the suspect to years of large-scale and systematic violence in the Stockholm capital region. Police in southern Stockholm pointed to his alleged role in that violence, saying he had been tied to it for several years. The detained man’s arrest status is described as custody following the operation. Police have not reported charges or a court outcome in the available details.
