Dr Voon was confronted by the boy's father outside the toilets, who grabbed him by the arm and yelled at him to show him what was on his phone
The child psychiatrist, Aaron Voon, was allegedly
caught filming the young boy in the bathrooms of a movie theatre in Canada.
According to The Global News, Mr Voon, 41, from Perth, Western Australia got in a confrontation with the boy's father outside the toilets at West Edmonton Mall’s Scotiabank Theatre on May 22.
The boy's father can be heard saying to the camera'Is this recording?'
Footage shows the father grabbing hold of Mr Voon's arm, before he tells the camera that Mr Voon was in the bathroom and had put his camera down next to his son.
The two men then demand for Mr Voon to 'show us your camera'.
'You were caught red handed with your camera angled when some boy was peeing' one of the men is heard yelling at Mr Voon.
The father and bystanders are said to have restrained Dr Voon (pictured on the floor) until police arrived
The footage of the incident was later posted online by a local news site.
Mr Voon had reportedly been watching a screening of The Angry Birds film before the incident took place.
He was arrested by Canadian police and faces charges of possessing child pornography, making child pornography and voyeurism.
WA Today reported that administrators a Dr Voon's pediatric clinic, the Successful Development and Therapy Clinic in Cockburn Central, emailed parents and industry peers a message from Dr Voon.
'Dear colleagues, patients and family,' the message reportedly read. 'A most terrible thing has happened with me in the past week whilst overseas which I will need to manage urgently... I will have to cease practice immediately indefinitely.
'For patients and family I am so sorry for leaving you so suddenly. I can honestly state that these issues have been TOTALLY separate from work and I have always provided you and your children with the best possible, safe and appropriate care.
'For colleagues, I seek your urgent support in taking over care ... my deepest apologies again and grateful appreciation for the past opportunity to work together.
'I hope that I will have the chance to work solidly on my personal issues and start afresh some time in the future.'

According to Daily Mail, when the clinic was contatced, an automated message said that due to unforeseen circumstances, the clinic would be closed indefinitely.
Dr Voon reportedly specialises in treating prepubescent children with social, emotional and behavioural issues and conditions including depression, anxiety, ADHD and autism.
There was apparently a three-month wait-list for appointments at his clinic, which range from $750-$990 for 90 minutes for initial consultations, and $395-$445 for subsequent appointments.
A spokeswoman for the Department of Foreign Affairs and Trade said the government was providing consular assistance to an Australian man who had been detained in Canada.
There is no suggestion or evidence that Dr Voon has been involved in illegal activity in Australia.
