A man who killed a commuter and injured three others in a knife attack at a railway station near Munich suffered from psychological problems and drug addiction, state officials say.

The man attacked four people shortly before 05:00 (03:00 GMT) yesterday at Grafing station. One of the victims died of his wounds in hospital.

A 27-year-old German man was eventually overpowered by police and arrested.
Some witnesses said he shouted “Allahu akbar” (“God is great” in Arabic).

But a spokesman for Bavaria state’s interior ministry said, “so far we have no evidence for an Islamist motive”.

“We have found the man had psychological and drug problems,” Oliver Platzer told AFP news agency. He said the investigation was continuing.

The suspect has been identified as a German national, apparently from the Hessen area of central Germany. Earlier, an Upper Bavaria police spokesperson said that a “political motive” had not been ruled out.

Bavarian Interior Minister Joachim Herrmann described it as a terrible attack and said a second victim had suffered life-threatening injuries.
