Sick child porn monster surrenders to police : BKA spokesman Christian Brockert told BILD: "The suspect handed himself in at midday. Investigations will now have to continue."

The BKA (Bundeskriminalamt, the German Federal Criminal Police Office) led a hi-tech search for the monster, releasing the footage of him molesting children

He sexually abused children as well as producing and circulating child porn.

Detectives used 42 videos to help them identify the man. The footage shows him sexually abusing between two and nine boys, aged five to seven. The footage was shot in various rooms and the man occasionally uses violence against the children.

The BKA believes the videos were made in 2006 and were circulated over the internet. The victims today would be between eight and ten years old.

One of the boys was called Marcel in the video, another Pascal. Some of the victims could also be brothers.

The video was made public on Wednesday on TV programme ‘Case Files xy…unsolved’ on the ZDF network, and has seemingly helped investigators to capture the fiend.
