A supervisor at an open-custody youth facility, southwest of Peterborough, has been charged with three counts of both sexual assault and sexual exploitation.

Provincial police began an investigation Aug. 4 into actions toward three female youth at Oakwood House in Millbrook.

Forty-four-year-old Daniel Melnichuk, of nearby Galway-Cavendish-Harvey township, has been charged.

He will appear in Peterborough court on Sept. 18.
