INTERPOL is seeking the help of the public to try to identify this man, photographed sexually abusing children in a series of images posted on the Internet.

The photos shown here are from a series of around 200 pictures involving 12 different young boys, believed to have been taken in Vietnam and Cambodia in 2002 or 2003.

These pictures have been produced by specialists from Germany’s federal police force, the Bundeskriminalamt, working from originals found on the Internet, which had been digitally altered to disguise the man’s face.

Extensive police efforts worldwide to identify the man have so far failed and Interpol is now enlisting the support of the media and the public to help identify him as a priority.

Anyone with information on his identity or whereabouts should contact their local police or INTERPOL’s Trafficking in Human Beings Unit via email .
