A Guelph high school teacher has been charged after a sexual misconduct investigation.

Guelph Police began the investigation on Dec. 10.

As a result, Justin Lenssen, 32, has been charged with possession of child pornography, sexual exploitation, luring a child and making explicit material available.

He appeared in court on Tuesday.

A letter from the Wellington Catholic District School Board confirmed that a teacher was arrested and charged, though it did not identify Lenssen explicitly.

“Earlier today we learned that Guelph Police Services arrested and charged a teacher who is an employee of the board,” an open letter from the Wellington Catholic District School Board read in part.

It went on: “The staff member is no longer at work. As this is a personnel matter, privacy laws prevent any further public comment.”

Parents or students who have had any interactions of concern with Lenssen are asked to contact the investigating officer, D/Cst. Joel Apps.

Anonymous information can be provided by calling Crime Stoppers.
