A German school teacher is suspected of cannibalism in Berlin where police believe he murdered a man he met on a dating site before eating his remains. 

The suspect, Stefan R, was arrested on Thursday after fleshless human bones were found in a park and sniffer dogs led detectives to his apartment in the German capital. 

Investigations revealed that the 41-year-old had searched for cannibalism-related content online and had once engaged the internet on the question of whether a person could survive after having their penis cut off, according to Bild.
