BERLIN, Germany (CNN) -- A suspected pedophile surrendered to police after German law enforcement published clips from videos of child pornography allegedly showing the man.
The German Federal Criminal Investigations Office also posted several photos and audio samples of the man's voice as they reached out to the public for clues leading to his arrest.
Along with the videos, the agency also posted screen grabs from the videos showing the details of the apartment where the films were shot.
The suspect turned himself in but refused to give any further details of his identity, investigators said in a news release.
Police said they found about 42 videos in which the suspected pedophile abused children, believed to be between the ages of 5 and 7 at the time.
Police think the videos were filmed in 2006 and that the victims would now be between 8 and 10 years old. The Investigator's Office said the man used violence against the children in some of the clips.
The German Federal Criminal Investigations Office has been using technology to combat child pornography for several years.
In 2008 the agency unscrambled photos of suspected Canadian pedophile Christopher Paul Neil which later led to his arrest in Thailand.
