A German man has been arrested after several people were stabbed at a train station near Munich early Tuesday.

One victim died in a hospital and three other people were wounded.The German authorities say they do not the believe the attack was linked to Islamist terrorism and they believe the suspect has mental health problems. 

The assailant made "politically motivated comments" as he attacked, Ken Heidenreich, spokesman for the Munich prosecutor's office in charge of the case, told The Associated Press.

He said his office was investigating witness reports that he yelled "Allahu Akbar," Arabic for "God is great."

"It's going in that direction," Heidenreich said of his office's initial information following the stabbing at the Grafing Bahnhof station, some 30 kilometers (nearly 20 miles) east of Munich.
