Hypnotist filmed himself sexually abused 19-year-old patient Police discovered the footage, along with 40,000 child pornography images, on his computer, in July 2010. A registered member of the Academy of Hypnotic Arts, he had R. Hyp. and R Chi C. after his name, Sherwin, 47, charged £95-an-hour. James House, prosecuting, said that Sherwin had "preconditioned her" in previous sessions before the abuse. He said that he had warned her that during the session she might feel sexually aroused "but shouldn't worry about it." A report from Liverpool University Psychology Professor, Graham Wagstaff, who is an expert in hypnotherapy, described Sherwin's behaviour after seeing the footage as "irregular in the extreme," clearly breaching the profession's self-regulated code of conduct. The images of children were among half a million legal adult pornographic images Sherwin had also downloaded. Judge Simon Hammond imposed a restraining order forbidding any contact with the victim and banned him from ever working with children. He will be on a sex offender register for 10 years. Jailing Sherwin for 18 months, Judge Hammond said the victim was "a vulnerable, gragile young woman." He added: "I'm concerned about the lack of formal training required and lack of regulation for people who work as hypnotherapists."
