A German man was frustrated with the police's inability to stop his 17-year-old daughter from seeing her 57-year-old boyfriend. So he took matters into his own hands, and cut off the boyfriend's balls with a bread knife.

You know how awkward it is, meeting your girlfriend's dad? Usually, though, it's not this awkward. Or bloody! Forty-seven-year-old Helmut Seifert, a German man born in Russia, was feeling a bit testy about the fact that his daughter was dating a man forty years her senior—something he learned, bizarrely, through an anonymous phone call. He was also not pleased that the police wouldn't do anything about it. So he went a little nuts:

"The man then recruited two work colleagues at his factory and then went to the house of the victim," said police.

"The man was forced to remove his trousers and, fully conscious, he was castrated. The severed testicles were taken away by the perpetrator."

The man was close to bleeding to death but managed to call police. His life was saved but he remains a eunuch for life.

Seifert, clearly a bad egg, has pleaded guilty and will stand trial for attempted murder.
