(Apichart Weerawong/Associated Press)Christopher Paul Neil of Maple Ridge, B.C., who worked as a teacher in different parts of Asia before his arrest last October, pleaded guilty in May to sexually abusing the Thai teen and faces up to 10 years in prison.

The 33-year-old Neil admitted through a translator that he took the photos, but said he did not post the pictures online.

He pleaded not guilty in early June to similar charges involving the teen's brother, who was nine years old at the time of the alleged offence. He faces up to 20 years in that case, which goes to trial on Oct. 7.

Neil became the subject of an international police search last year after Interpol released censored photos of him allegedly engaging in sexual acts with young boys from different parts of southeast Asia, including Cambodia and Vietnam.

The photos were found online in 2004, but the face of the perpetrator was digitally obscured by a swirl shape. Interpol was able to unscramble the images with the help of German police computer experts three years later, and circulated the pictures publicly.

Hundreds of tips were received and Neil was arrested 11 days after the Interpol appeal was launched.

Neil taught at various schools in Thailand, South Korea and Vietnam since at least 2000.
