PARIS (AP) – 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 went public after efforts to track down the man through its network ran dry.

Interpol said it now knows the suspect’s name, nationality, date of birth and passport number, but it did not release that information. It said the man flew from Seoul, South Korea, to Bangkok, Thailand, last Thursday, with security cameras documenting his arrival at Thai immigration.
