Dozens of people walk past a potential sexual assault in Greece

A social experiment consisted of two actors testing the Greek public to see how they'd react to a woman crying for help and a man shouting, and a staggering 85% completely ignored it and didn't even phone the police with only 25% stopping to help her.

The experiment was filmed on YouTube but is being kept anonymous to protect the actors' privacy. One actor said: "I can't believe that 85% of the bystanders refused to help a potential rape victim; they didn't even phone the police, and this just shows how sick our society is. If you see a sexual assault, say something, and call the police."

Anyone witnessing a sexual assault must immediately call the emergency services and, if safe to do so, should try to intervene and perform a citizen's arrest on the offender until officers arrive on scene. However, if the assault happened in the past, the police should be contacted via their non-emergency number — which is currently 101 in the UK — so that they can try to hold the offender accountable.
