A former Ohio attorney has been sentenced to 12 years in prison for hypnotizing unwitting female clients for his sexual gratification.

Fifty-nine-year-old Michael Fine was sentenced Monday in Lorain County after pleading guilty in September to kidnapping and attempted kidnapping charges involving six women. The judge ordered him classified as a registered sex offender.

Authorities say Fine's criminal activities were exposed in 2014 after a client who suspected she'd been hypnotized recorded two telephone conversations during which Fine used explicit sexual language before ending calls discussing legal matters. Publicity prompted other women to contact authorities with their suspicions.

Defense attorney Robert Housel says Fine has had difficulties in his life, voluntarily gave up his law license and acknowledged what he had done by entering guilty pleas.
