The suspect is a 27 year-old German citizen.

The AP reported:

A German man was arrested after several people were stabbed at a train station near Munich early Tuesday, authorities said. One victim died in a hospital and three other people were wounded.

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 he yelled “Allahu Akbar,” Arabic for “God is great.”

“It’s going in that direction,” Heidenreich said of his office’s initial information. Officials also raised the possibility that the man was mentally disturbed.

Heidenreich said, however, that the suspect is a 27-year-old German citizen, with a German-sounding name.

“We have no information that he is a recent immigrant here or of that background, but we don’t know for sure at the moment,” he said, adding that the man didn’t live in Bavaria.

The suspect attacked several people with a 10-centimeter (four-inch) knife at the Grafing Bahnhof station, police said.
