A child psychiatrist who filmed a boy in a public washroom at West Edmonton Mall has pleaded guilty to a string of child pornography charges, according to a published report in Australia.

Perth Now reports that Aaron Voon, 41, pleaded guilty Thursday in Perth Magistrates Court to nine separate charges, including filming boys at urinals and producing and possessing child pornography material in four countries: Canada, the United States, New Zealand and Australia.

Voon was arrested after a confrontation at West Edmonton Mall in May.

A 10-year-old boy's father confronted Voon after he saw Voon place a camera next to the washroom stall the boy was using.

Voon is out on bail and will be back in an Australian court Jan. 27 for sentencing.
