A suspect has been detained, a police spokesperson told CNN on Friday. It is still unclear exactly how many people have been injured and how severe their injuries are.
“Hamm Police has a major operation ongoing in the area of the Hamm-Lippstadt University. Several people were injured with a knife. The perpetrator has been detained. We are at the scene in numbers and ask you to avoid this area,” Hamm police said on their official Twitter account Friday.
