BERLIN (Reuters) - A child porn offender in Germany turned himself in to the police after mistaking an email he received from a computer worm for an official warning that he was under investigation, authorities said on Tuesday.
The trap was set when the man got an email saying "an investigation is underway," that listed the sender as Germany's Federal Criminal Police Office (BKA). Police charged him after finding pornographic images of children on his home computer.
