According to the police, several people were injured with a “stabbing or cutting weapon” in an attack in a gym in Duisburg’s old town on Tuesday. So far there is no information on the number of attackers and injuries, said a spokesman for the responsible Essen police. The background to the crime is still unclear.

According to WDR, two perpetrators are said to have stabbed visitors in a gym. “Bild” reported that the police are assuming an amok act. Accordingly, the perpetrator or perpetrators should still be on the run.
