In 2000 Ronald Van Der Plaat became one of the country’s most infamous sex offenders when he was jailed for a litany of horrific abuse against his daughter spanning 23 years.

He started raping, sexually violating and indecently assaulting his daughter Tanjas when she was just 9 when the family were living in Vanuatu.

For the next 23 years, he would keep her as a sex slave, subjecting her to “bizarre and depraved” abuse which only ended when she became pregnant to him - not for the first time - and suffered a miscarriage.

Van Der Plaat would use handcuffs, chains and clamps on Tanjas during sadistic sex sessions.

He would ply her with alcohol and sedatives before sex - once resulting in an overdose that left her with a permanent heart problem.

In the latest episode of Herald podcast A Moment In Crime journalist Anna Leask looks back at the ghastly offending.

The episode also features first-hand accounts of the abuse from Tanjas, from her book Flight of the Dancing Bird which she released after her father was imprisoned. 

This episode contains references to physical and sexual abuse - and child abuse. It is suitable for a mature audience and may be upsetting. 

The episode also contains brief extracts from the book Flight Of The Dancing Bird, published by Tanjas Darke published in 2001 by HarperCollins. The book is available at local libraries and can be purchased online.
