The clip was launched as part of a campaign involving the police and Transport for London.
A video about a female commuter being sexually harassed on the London Underground has been watched more than 100,000 times in just a couple of days.
The clip, “Report It to Stop It”, was produced by Transport for London as part of its Project Guardian campaign in association with the British Transport police, the Metropolitan police, and the City of London police.
The campaign was set up in 2013 after it was revealed that 90% of those who experience unwanted sexual behaviour on public transport don't report it.
The video depicts a woman being groped by a man while travelling on the tube.
As the scene plays out, narrator Olivia Coleman repeatedly asks: “Would you report it?”
At the end, the video flags up how victims can report harassment.
