Four people were seriously stabbed in an attack on a gym in the center of the western German city of Duisburg on Tuesday, police said.
“Three of the victims suffered life-threatening injuries” and another person suffered serious injuries, police said on Twitter. All the injured are German citizens and have been taken to hospital.
Public broadcaster WDR previously reported that two assailants stabbed gym goers.
On the other hand, the newspaper “Bild” reported that, according to the police, one or more attackers are still at large and are being sought.
Currently, a large-scale police operation is underway in the old town of Duisburg, in which the security guards of the nearby Essen also participate. The police have called on citizens to avoid the vicinity of the scene.
