A RUSSIAN paedophile has been jailed for 22 years and six months for committing more than 900 rapes and sexual attacks on underage schoolgirls who were in his foster care.

Gold-toothed Viktor Lishavsky, 37, treated the victims as his “personal harem” and “sexual slaves”, a court heard.

The evil Lishavsky admitted his guilt to all charges but refused to give evidence at his closed-door trial in Komsomolsk-on-Amur in the Russian Far East, The Sun reports.

The former head of an evangelical church in the town of Amursk, Lishavsky is believed to be the worst convicted paedophile in Russian history.

A court in Komsomolsk-on-Amur found the “monster” guilty of more than 900 counts of rape and violent sexual acts mostly against girls aged around 13.

He will serve his sentence in a “strict regime” penal colony, after which he will face another two years unable to leave the town where he lives and reporting regularly to police.

He is banned from working with children for a further two decades after his release.

Lishavsky and his wife Olga had three children of their own and fostered nine more.

He was caught after a five year reign of sexual terror when one of the foster girls confided in Olga, who had been entirely unaware of his abuse, the judge was told.

Other victims then corroborated the accusations against him.

By day he ran a shoe repair shop but at night he regularly attacked the adolescent girls.

He was found guilty of the rape of minors, including acts committed with “particular cruelty”, and forcing his underage victims to commit acts of a sexual nature, according to a statement from the court.

He was also convicted of indecent acts such as using violence against girls under 16 and torture.

State prosecutor Tatyana Filatova said: “None of the girls complained because each considered him a father.

“Some told each other about what had happened, but they were not in a hurry to complain to their mother.

“The children were taken from an orphanage, and none of them wanted to lose their family.

“They finally had both a mum and dad. The terrible details came to the surface only later.

“After discussing everything among themselves, one of the girls said that she was not afraid of her father and would tell everything to her foster mother.

“The mother, in turn, went to the police.”

The prosecutor said: “All these years, the adoptive mother did not see anything, because she often was in hospital with her son.

“In court, they tried not to go deep into the details of the crimes in order not further harm the victims.”

The hearing was held behind closed doors but a charge sheet showed he had been accused of 248 rapes plus 358 “violent sexual acts” against girls aged 13 or under.

He faced another 22 accusations “violent acts of a sexual nature” against girls below the age of 14.
