A Dutch children's rights organization is warning of an epidemic of minors being paid to perform sexual acts via webcams and is urging police around the world to crack down on the practice.

Terre des Hommes, a Dutch-based organization that works to stop child exploitation around the world, said Monday that to gauge the scale of the problem it created a computer-generated 10-year-old Philippines girl called Sweetie. It says she was bombarded with offers in an online chat room to pay for webcam sex shows.

Terre des Hommes director of projects Hans Guyt says, "If we don't intervene soon, this sinister phenomenon will totally run out of control."

The organization says it identified 1,000 online predators during a 10-week investigation and will hand details to Interpol.
