Police in North Yorkshire, U.K., have reported that three men have fallen victim to sextortionists.

A women calling herself Cathy Wong befriended the men on Facebook and convinced them to Skype with her. She then enticed each of them into performing an indecent act, which was recorded on video.

After making the recordings, she asked them to send her sick grandmother £3,000. The men refused. Ms. Wong then told them that she would post the videos to YouTube if they didn't pay up.

Detective Sergeant Rebecca Dyer of York CID said: "This scam is causing considerable distress to the victims and I urge anyone who uses any kind of social networking site to be very wary of what they are getting into.

"I am concerned that there are other victims of this scam who are too embarrassed to come forward about what has happened. I urge them to please get in touch with the police. Your information will be dealt with in the strictest confidence and with sensitivity. Please do not suffer in silence," he added.
