In an ICE, three men are victims of a knife attack on Saturday morning.
The 27-year-old perpetrator, who comes from Syria, was arrested.
There are still no definitive findings on the motive for the crime.
Neumarkt - After the knife attack in the ICE 928 in Bavaria, the police do not assume a terrorist attack.
There are "no indications of an Islamist background," said criminal director Sabine Nagel on Sunday in Neumarkt in the Upper Palatinate.
According to initial findings, no indications of possible accomplices or confidants have appeared so far.
The suspect, a 27-year-old, had randomly attacked fellow travelers on Saturday in the ICE Passau-Hamburg.
A folding knife with a blade length of eight centimeters was seized as the murder weapon.
The suspect who came to Germany in 2014 and was born in Syria lost his job the day before the crime, according to the police.
