"Four people injured, some seriously, currently no more danger, perpetrator dead - single perpetrator assumed," police said in a tweet.
A spokesman told Reuters the gunman fled the lecture hall before turning his gun on himself.
He added that the man's motive was unclear. Mass-selling newspaper Bild reported that the gunman was a student.
