The leader of a satanic sect that practiced orgies as part of the initiation of adepts has received a 20-month prison term.

Aleksandr Kazakov, 25, was found guilty of creating an organization that violated human and civil rights, and of indecent actions directed at a minor. His right-hand man, Denis Danshin, 23, received a year-and-half suspended term, reports Interfax news agency.

The two men organized the so-called “Noble Order of the Devil” or “Nobilis Ordo Diaboli.” Adepts, who were mostly high school or university students recruited via Internet, gathered in secrecy to perform death-themed rituals and indulge in promiscuity.

Prosecutors also accused Kazakov of rapes and beatings of dissident members, but failed to gather evidence.
