Police are investigating a torrent of threatening and racist abuse against a Frenchwoman on a Melbourne bus that was caught on camera and went viral on YouTube.
The woman and a group of friends were returning from a day at the beach when one of them began singing in her native tongue, which prompted an angry reaction from some passengers on the packed bus.
One aggressively demanded she "speak English or die" and then threatened to cut her breasts off. Another man pushing a stroller joined in, shouting: "I'll f*****g box-cutter [knife] you right now, dog."
The woman was then told: "Everybody on the bus wants to kill you" before the incident ended with a bus window being smashed.
The woman targeted, Fanny Desaintjores, told The Age newspaper she and her friends were terrified they would be assaulted.
"I realise that maybe we shouldn't sing on public transport, but I think that's insane that they reacted like that. We're all adults," she said.
Parts of the incident were caught on camera by stand-up comedian Mike Nayna and the footage has been viewed thousands of times on YouTube, with the story picked up by French newspapers.
