One man has died and three other people were wounded in a knife attack at a Bavarian train station in the early hours of Tuesday morning.

The incident in Grafing, near Munich, saw a man attack four communters shortly before 5 a.m. local time.

Police spokeswoman Michaela Grob said a man had been arrested and authorities were trying to identify him. The town's mayor, Angelika Obermayr, told Sueddeutsche Zeitung the man was a German national.

Some witnesses said he shouted "Allahu akbar" ("God is great" in Arabic), the BBC reported, while police said a "political motive" had not been ruled out.
