Shortly before 9 a.m. on Saturday, police received a call alerting them that a man with a knife was attacking passengers on Intercity Express train 928, which was traveling from Regensburg to Nuremberg in southeastern Germany.
Using an 8-centimeter (3.1-inch) folding knife, the suspect first went after a 26-year-old man in the same train car, wounding him in the head. The suspect then attacked a 60-year-old man, who was wounded on his head and torso, and another 60-year-old man, who also was wounded.
At that point, the suspect fled to another train car and stabbed a 39-year-old man on his upper body.
All four victims were from the Regensburg and nearby Passau area and were taken to nearby hospitals.
Police said the suspect, a Syrian citizen, came to Germany in 2014 and was granted asylum in 2016. He had been living in Passau. Investigators said an initial evaluation suggested he suffered from mental illness.
The high-speed train pulled into Seubersdorf, a station between Regensburg and Nuremberg, and police officers quickly arrested the suspect “without resistance.”
