Father castrates daughter's boyfriend with bread knife December 14, 2010 - 8:31AM A German father was so angry his teenage daughter was dating a man 40 years older than her that he castrated the boyfriend with a bread knife, police say. Helmut Seifert, 47, who was originally from Russia, complained to police in Bielefeld, north-west Germany, when he found out about his 17-year-old daughter's relationship with Phillip Genscher, 57, London's Daily Telegraph reported. But when police told him they could do nothing, Mr Seifert recruited two colleagues at his factory and went to pay Mr Genscher a visit.

Mr Genscher lost a lot of blood - and his testicles - but survived and was able to call police for help. Mr Seifert will go on trial for attempted murder next year after pleading guilty. But he remained defiant, defending his actions and refusing to give up the names of the colleagues who helped him. "I received a phone call anonymously that my daughter was involved with a guy 40 years older than her. You said you couldn't stop him – so I did," he told police. "I saw it as my duty as a father."
