Sean Tari, 40, a general practitioner in northern New South Wales, posted three videos on YouTube last month, showing himself posing as a female prostitute, ordering pizzas without bases and asking a medical centre receptionist for a rectal examination with a Chinese doctor because "they have smaller fingers".

Dr Tari, who practises at the Western Plains Medical Centre, removed the videos, listed under the pseudonym Funnisean, after he was contacted by detectives, but the behaviour has angered a local MP, Dawn Fardell, who says business operators should not have to put up with "this nonsense".

"This man is 40, not 12, and he is counselling people who have their own problems. He's welcome here in Dubbo but he needs to get some help because as a leader in the community this is not acceptable behaviour," she said.

In the first video, Dr Tari is seen ringing a medical centre in Eastwood, telling the receptionist his mother had just died and he needed a rectal examination, but wanted to see a Chinese doctor because the last time he had a similar exam at the centre a Bangladeshi doctor "with big fingers" had caused him pain.

In another, he calls Domino's Pizza in Dubbo, and attempts to order a Hawaiian pizza without ham and pineapple and another without a base. After tying up the operator for several minutes, he asks for the order to be delivered to an address in Sydney.

In the third video, Dr Tari calls a Parramatta brothel, called Midnight Delight, and impersonates a woman "just off the boat". He tells the receptionist he is looking for work as a prostitute and asks about pay rates. He is offered an interview, then hangs up, exclaiming "yay, I am a prostitute".

Dr Tari has a website promoting his "anti-religious views" and his work as an author, which he says is an outlet for his "mental diarrhoea".

He claims to have had 27 books published, including one called Satanica - Encyclopedia Of Satan.

He said he was arrested in 1999 by the Iranian intelligence service and suffered 13 months of torture before escaping to Australia.

"I feel more safe among kangaroos," he says on his site.

Dr Tari says he invented an electronic scope with no tube and a gloved bag to prevent anthrax contamination but both were "produced later under somebody else's name".

When contacted by the Herald, he would not comment.

Police are yet to confirm if charges will be laid.
