Fabian Meharry was confronted by girls he threatened to expose.

Fabian Roy Meharry, 28, engaged in sexual chat with his victims, who were as young as 11, then blackmailed them into sending him nude images or videos. Meharry, a well-known BMX rider in Echuca, has pleaded guilty to 62 abuse charges for the period between 2006 to 2015.

The online predator compelled some of his victims to perform sex acts with animals and objects which he then recorded via Skype or webcam. He also coerced one girl into having sex with her brother, the Victorian County Court was told on Monday.

If the victims failed to comply with his requests to send more explicit photos or videos, he threatened to post explicit material of them online, tell their parents, or self-harm.

He told one girl: “If you don’t show me, then I will put photos of you online and make it go viral.” Meharry met three of his victims in person and performed sex acts with them. One of his victims, aged 14 when abused, told the plea hearing she blamed herself and now suffered post traumatic stress.

“I’ve never been made to feel so belittled or ashamed by anyone. You broke me,” she told Meharry.

“You saw my weaknesses and used every single one against me.

“No one has the right to take someone’s innocence.”

Judge Liz Gaynor told the girl it was not her fault and praised her for her bravery in giving evidence.

“That says a great deal to me about your strength and intelligence,” she said. Meharry was already a registered sex offender when he committed some of the crimes, having been convicted of sex and indecent acts with a minor and possessing child pornography.

His latest charges included the persistent sexual abuse of a child under 16, compelling sexual penetration, sexual penetration of a child under 16, producing child pornography and using a carriage service for sexual activity. The plea hearing is continuing on Tuesday.
