Paris ? First Interpol unmasked his face. Now it knows his name.

The international police organization, working off tips from people who responded to a global appeal for help, said Monday it has identified a suspected pedophile shown in Internet photos abusing young boys.

The man, whose face initially was disguised behind a digitalized swirl, is now thought to be on the run in Thailand, Interpol said. He is said to be an English teacher at a school in South Korea.

The man was allegedly shown sexually abusing 12 young Vietnamese and Cambodian boys, apparently ranging in age from 6 to early teens, in about 200 photographs posted on the Internet. Using techniques that neither they nor Interpol would discuss, German police recreated an image of the man’s face and released four reconstructed photos of him last week.

Interpol said more than 350 people then supplied tips to authorities worldwide. Officials are still collecting and analyzing evidence to bring charges against the man if he is arrested, it said.
