Paris police were late on Wednesday, searching for a man who shouted to a little Jewish girl "Hitler was right."
The incident in a Metro was filmed by a young woman who said she was complaining about him to the police. The clip of his assault was posted on social media and the police said they had launched an investigation and are sure they will apprehend the man quickly.
The young woman who was the only one present who came to the defense of the Jewish family told the police people were afraid to intervene.
"I boarded the metro and had my earphones on with music when this man came on to the train and started cursing and spitting," she said. "He shouted at the Jewish family that all Jews should be killed. "He said they were a bunch of bastards, and are are committing crimes against humanity and spat on them."
