In an unprecedented move, the global police body launched the worldwide search for the man shown sexually abusing young boys in images believed to have been taken in Vietnam and Cambodia, possibly in 2002 and 2003.The pictures had been digitally altered to disguise the man's face, but computer specialists at Germany's federal police agency worked with Interpol to produce identifiable photos. The man is thought to be a European aged around 35-40, says a Swedish police officer. Interpol's database of child sex abuse has so far helped police identify and rescue almost 600 victims from 31 countries.
