Police investigate the scene of multiple stabbings at a train station in Grafing near Munich, Germany.

One man was killed and three people injured during a knife attack at a train station in southern Germany Tuesday morning, the Bavarian Criminal Office says.

Police have arrested a 27-year-old German man in connection to the attack, a police spokesman said, adding that a political motive could not be ruled out.

The attack happened shortly before 5 a.m. local time (11 p.m. ET) in Grafing, 23 miles (37 kilometers) east of Munich, officials said.

The dead man, a 50-year-old, was inside a train bound for Munich when he was stabbed, police said. He later died in a hospital.

Three other men were injured, one of them seriously. Officials gave the injured men’s ages as 58, 55 and 43.

Police arrested the suspect near the station shortly after the attacks, said a police spokesman. A knife with a 10-centimeter (4-inch) blade was recovered, he said.

Police are currently questioning commuters who saw the attack take place.

The scene of the attack was cordoned off as police carried out inquiries.

Footage from the scene showed bloodied footprints leading out of a train carriage at the station, and small puddles of blood on the platform.

The Bavarian Criminal Office has taken up the investigation.
