A Lehigh County karate instructor accused of sexually assaulting one of his young female students pleaded guilty in court on Monday.

Shahrokh Mahrkar, who pleaded guilty to a corruption of minors charge, was sentenced to five years probation, the first three months of which will be on house arrest.

Police charged Mahrkar with having sexual contact with a student for two years starting in 2009, when she was 12 years old.

Mahrkar was working at the American Mixed Martial Arts Dojo in Trexlertown at the time.
