— Paul Fegmann (@Pauli_Feger) April 7, 2018Police said they were not looking for further suspects after the driver took his own life after the crash, but on Twitter they urged people to avoid Muenster city center. The man presumed to have driven a van into a Muenster restaurant on Saturday was a German with psychological problems, the Sueddeutsche Zeitung newspaper reported in its online edition.The man had no terrorist background, the newspaper added, citing information it had obtained but giving no specific source."The danger is over," the police spokeswoman said.The incident came one year to the day after a truck attack in Stockholm that killed five people, and also evoked memories of a December 2016 truck attack in Berlin that killed 12 people. Anis Amri, a failed Tunisian asylum seeker with Islamist links, hijacked a truck on Dec. 19, 2016, killed the driver and then plowed it into a crowded marketplace, killing 11 more people and injuring dozens of others."I am shocked by the news from Muenster," said Andrea Nahles, parliamentary leader of the Social Democrats, junior partner in Chancellor Angela Merkel's ruling coalition."My thoughts are with the victims and their relatives," she added. "I hope that our authorities can quickly clarify the background to this incident and wish the local forces much strength for their work."
