A German man could face six months in prison after selecting an Adolf Hitler speech as his mobile phone ringtone.

According to the Telegraph, the 54-year-old's Nokia gave forth several times during a train journey in Hamburg, with Adolf pledging the "destruction of world Jewry".

Fellow passengers alerted the police, who cuffed the man at his destination. The Führer fan's allegiance was confirmed by "swastika stickers and photos of Hitler" on the phone and the words "The greatest commander of all time".

He's charged with violating the German constitution, which takes a dim view of "public displays of the Nazis and all their works". ®
