Four of the nine injured were said to be seriously wounded, but police say none of the victims are in life-threatening condition.
News site Spiegel Online identified him as Fatmir H. and said he had told investigators that he had hoped to be shot dead by police following the random attack.
With screams echoing around the station concourse and the wounded bleeding on the ground, police chased the man along railway tracks until he leapt off a four-metre bridge to evade arrest.
Lying on the ground, the injured man told the first officers on the scene that “he had been ready to be shot dead by police,” said local crime squad chief Dietmar Kneip.
“We call that 'suicide by cop',” he told a press conference. “But luckily we were able to arrest him.”
He suffered serious multiple broken bones from the fall, police said, and was taken to hospital.
