A rapist driving instructor sexually assaulted a woman in his car during a lesson in Manchester.
Predatory Martyn Rees 'spent years abusing his position as a trusted driving instructor' to commit offences against learner drivers.
The Crown Prosecution Service (CPS) meanwhile said he used his job to 'sexually prowl on young females' - and revealed 29 mobile phone clips of Rees covertly recording intimate body parts of young driving students were found.
Rees was also convicted of attempted sexual assault of a woman during a lesson in Manchester and of making an indecent image of a teenage girl from Manchester.
The sex assault happened during a lesson and was committed against a woman in her 20s, police said.
Rees - who has not been able to operate as a driving instructor on either a paid or unpaid basis since March 2018 - pleaded not guilty to the three offences, but was found guilty on Friday after a trial by a jury at Stoke-on-Trent Crown Court.
He was also found guilty of numerous sexual offences, including the rape of a teenage girl in his car; two counts of sexual activity with a child; five counts of making indecent photographs of a child; and possession of an extreme pornographic image.
Rees, from Stoke-on-Trent, pleaded guilty at an earlier hearing to assault by penetration; two counts of sexual assault; four counts of making indecent photographs of a child; and two counts of possessing cannabis.
The incidents took place in Newcastle-under-Lyme, Cheshire and Manchester between February 2015 and March 2018.
He was arrested in March last year following reports of the rape of the teenage girl in Newcastle-under-Lyme.
