This story may help bring a serial sex criminal to justice.
The man appears in around 200 photographs featuring abuse of 12 young boys, which investigators believe were taken in Vietnam and Cambodia, possibly in 2002 and 2003.
The pictures had been digitally altered to disguise the man's face with a swirly pattern, but computer specialists at Germany's federal police agency, the BKA, worked with Interpol's human trafficking team to produce identifiable images.
To see pictures of this man go to the homepage of Interpol. While the pictures stop at 2003, the crimes likely won't stop until this man is apprehended.
