Police in Nova Scotia have charged a principal with a number of offences relating to an alleged sexual assault of a minor in 1998.

Doug Keyes, 51, of Gypsum Mines, is principal of Avon View High School in Windsor. He became the principal at the school in August 2009.

Windsor RCMP announced the charges on Friday, saying they received a complaint from the alleged victim last month.

The Annapolis Valley Regional School Board says it's co-operating with the investigation.

"Our primary concern is with the safety and well-being of our students. We understand that this has an impact on all members of the school community. We are aware that the complainant is not a current student at the high school," the board said in a statement.

The board informed students about the charges on Friday morning and sent letters home to parents.

Keyes was placed on administrative leave on Thursday. The board said it will do its own investigation.

Keyes is due in Windsor provincial court on Jan. 3 to face charges of:

  • Sexual assault,
  • Sexual touching,
  • Breach of trust,
  • Using a computer system with intent to commit an offence,
  • Producing a false document.

Ryan Armstrong, who graduated from Avon View High School last year, said Keyes was a principal who was always ready to help students in need.

"Mr. Keyes, he was always one of the best guys to me. He helped me out through school and stuff," Armstrong told CBC News.

"He's a pretty good, down-to-earth guy, good to joke around with and stuff. He actully taught me in one of my classes. You could joke around with him. If you had any problem, you could go tell him and he'd actually listen."
