An Australian court has heard that boys in Singapore are among the 47 victims of a paedophile known as “one of Australia’s worst sex offenders,” who used to travel through southeast Asia under the guise of sales and business work, only to sexually abuse boys aged 10-15.

Boris Kunsevitsky, 52  who had been born in Russia before migrating to Australia at the age of 12, seemed to have considered Singapore his “adopted home”. His last job in Singapore was as technical director of aesthetics products company, Esthemedica, where he began work giving technical advice since 2014.

Besides having abused his 47 victims, the paedophile had also taken over 3,300 photographs and videos of himself performing sexual acts with at least 25 of his young victims, and had distributed them online. He had also forced some of the children to have sex with other young boys.

Kunsevitsky admitted to a lengthy list of charges yesterday (May 21) that included 25 counts of having sex with children outside Australia and 12 counts of getting a child to have sex with another child.

The child pornography videos Kunsevitsky had circulated online caught the attention of Germany’s police who investigated him and subsequently involved Australia’s police. The Australian authorities, who began investigating the suspect in 2016 while he was in Singapore, arrested him when he returned to Melbourne in 2017 after finding child exploitation material on his phone.

The Australian police soon received Kunsevitsky’s possessions from Singapore and discovered his database of abominable material going as far back as 2001, and showing him having sex with young boys, and having his victims perform sexual acts on one another.

The police also found over 37,000 child pornography images Kunsevitsky had downloaded from the Internet.

The court heard that in some of his own recordings, the accused could be heard telling his victims to smile and relax when they appeared to be in pain.

Kunsevitsky’s defence lawyer, however, claimed that the young victims were “simulating” pain. Asserting that such claims showed a lack of remorse, prosecutor Krista Breckweg labelled the acts “depraved and despicable.”

The accused, who is in remand pending sentencing, faces decades in prison.
