A priest who taught chemistry years ago at a Detroit Catholic school has been charged with child pornography crimes.

The FBI says the Rev. Richard Kurtz secretly recorded hockey players in the locker room at University of Detroit Jesuit High School during the 1998-99 season.

The 69-year-old Kurtz was arrested Monday in Dittmer, Missouri, and will appear in St. Louis federal court Wednesday. It wasn’t immediately known if he has a lawyer. He’ll eventually be transferred to Detroit.

The FBI says the Detroit case is based on child pornography discovered by priests in 2011 at Kurtz’ residences in Chicago and Clarkston, Michigan. He was arrested in Chicago that year on a sexual assault charge in Douglas County, Colorado, involving a minor in 2001.

Kurtz was placed on probation.
