A train conductor on a high-speed ICE train began to feel suspicious about a 22-year-old man who was spending a particularly long time in the toilet, a federal police spokeswoman told Spiegel Online on Tuesday.
She decided to open the door, only to find the bewildered man "as God had created him". Not only was the 22-year-old naked, he was also holding a kitchen knife - causing the conductor great alarm.
The conductor then alerted the federal police, who are responsible for overseeing train stations. The officers arrived to find the man in the toilet "stark naked" and shaving his pubic hair with the knife, according to Focus magazine.
"He was quite indignant, felt disturbed and reluctantly got dressed," a police spokeswoman said.
While shaving one's intimate regions in a train toilet is not illegal, the man was found to have not bought a ticket and was told to get off at Düsseldorf station.
But why couldn't the young man perform such personal grooming in the comfort of his own home?
The police spokeswoman said that at the time the man felt "unwelcome" at home, and so a bathroom was currently not available.
"But he groomed himself anyway," the spokeswoman said.
