A German man, who impersonated a doctor online and coerced women to electrocute themselves as part of fake pain therapy experiments, was sentenced to 11 years in prison Monday.

The man, identified as 30-year-old David G, a computer scientist, impersonated a doctor or a professor online. He told people that he was conducting a detailed study on pain therapy. He then used Skype to convince girls and young women to electrocute themselves as part of the therapy and offered them money for the same.

The women who agreed to be a part of the study used metal spoons to construct devices at home. They then strapped themselves to chairs and applied electricity. In some cases, the parents of the victims helped them in carrying out the therapy. David would observe them via Skype and also record the encounters. He would ask the victims to place the metal objects near their temples "meaning that the human brain was subjected to an electric current."

The prosecutors told the court that the man conducted the fake therapy as he derived sexual gratification from it. The court heard that David would get aroused by seeing the victims in pain.

He pleaded guilty to attempted murder along with other charges including misuse of title and grievous bodily harm.
