Police say a Barre, Massachusetts, sex offender failed to notify officials that he was working in a martial arts studio, despite his conviction of raping his karate students in 1991.
According to the Worcester Telegram, David Sanderson, 60, a Level 3 offender, never informed police of his latest job out of North Brookfield, which is required by law.
He was convicted in 1991 after pleading guilty to rape and related charges. He was sentenced to 20 years in prison.
A former police officer tipped officials off in May that Sanderson was working at Eternal River School and was teaching under a different name.
He was bailed out on $2,000 by his wife and is due in court on June 23.
