BERLIN (AP) — A man with a knife stabbed three people Friday in a town in southwestern Germany before being arrested, police said.

The stabbing happened in the Marienplatz square in Ravensburg, police wrote on Twitter.

There was no immediate word on the identity of the assailant or victims, or on a possible motive. However, police told the dpa news agency that there was no indication of any terrorist background.

The agency said one of the victims was in a life-threatening condition.
