A 21-year-old student from Birmingham posed as a gynaecological researcher in an online advert and lured women to his flat in exchange for £500.
According to a Daily Mail report, more than 200 women responded to the Gumtree ad. But only three agreed to be examined by Liam Ryan.
However, when he failed to handover the cash one of them informed cops.
Ryan pleaded guilty to two charges of sexual assault and three charges of engaging in sexual activity without consent at Birmingham Crown Court on Thursday, reported the website.
He was jailed for four and a half years, ordered to sign the Sex Offenders' Register for life and was made the subject of a ten-year sex offender prevention order, Daily Mail added.
