Trading standards are investigating a 'psychic surgeon' from Harrow following a BBC documentary on his work.

Gary Mannion, from South Harrow, was the subject of 'Gary: Young, Psychic and Possessed', a BBC Three programme aired on Tuesday night, in which he claims a spirit called Abraham helps him tend to people's ailments.

And now, in light of the show, Harrow and Brent trading standards officers will be looking into his practices - a year after he was ordered to take down a testimonial on his website that claimed he cured cancer.

During the one hour show the 20-year-old is seen treating clients with Alzheimer's, gall stones, and brain tumours using a form of psychic healing, which according to the programme can earn him up to £2,000 a week.

On his website he says that despite having no medical knowledge, except "basic first aid", he has a spirit called Abraham who "uses my hands to perform psychic surgery" and enables him to "see inside people's bodies".

Before each treatment Mr Mannion is required by law to preface his work with a disclaimer that informs clients that he has no medical knowledge and he is not offering a cure.

But in the documentary he said: "I make it very clear that I can't guarantee a cure.

"I'm not claiming anything. I'm passionate about what I do and I like it when clients come and say they're better.

"I'm confident with it..... [so] people [might] not listen to the disclaimer."

Speaking the day after the airing of the programme Bill Bilon the director of trading standards, said: "The documentary is being reviewed by trading standards regarding Mr Mannion's business and potential claims made.

"No complaints have been received by Harrow Council since the broadcast, though we can confirm trading standards officers visited Mr Mannion in February 2008 to provide guidance and advice.

"Mr Mannion was reminded to be compliant with the Cancer Act, which states it is illegal to claim to be able to cure the disease.
