A 30-year-old assistant professor who had been attending a conference at the Hamm-Lippstadt University of Applied Sciences has died from her injuries after an apparently random knife attack on students on Friday. The AFP news agency reports that a 22-year-old student suffered eight stab wounds to the stomach and needed emergency surgery, but her condition is not thought to be life threatening, while a 22-year-old man and another young woman of the same age, were less seriously injured. The suspect had earlier on Friday discharged himself from a psychiatric hospital where he had been staying after a suicide attempt.
