Calgary Police have arrested a man after he allegedly filmed a staff-only change room at a southwest recreation centre.

Police were called to the Canyon Meadows Aquatic and Fitness Centre on 89 Canova Rd. S.W. on November 30 after one of the workers at the facility discovered images of colleague changing in the women’s locker room.

Staff Sergeant Craig Skelton says that the images and videos were discovered on a portable storage device that was found in the parking lot of the facility. "Police were called after the storage device was found and through our investigation, we were able to identify four victims."

All four victims work at the recreation centre.

There is no indication on whether or not members of the public were incriminated in the footage.

Following an investigation, police arrested Donald Robertshaw, 60, on December 11.

Police say that Robertshaw worked at the centre and his job gave him access to take the photos.

He is charged with four counts of voyeurism.

Robertshaw was released on a promise to appear in court.

It’s not believed that any public change rooms were targeted but the investigation is ongoing.

"Our indications show that the images were recorded over a period in the month of November," Skelton says.

Police say the City of Calgary Recreation Department is aware of the situation and they expect they will move forward with measure to prevent such acts in the future.

Robertshaw is scheduled to appear in court on January 10, 2013.

Skelton says the best defence against these situations is to be aware of your surroundings. "If you see something out of place or doesn't belong, or nobody appears to own it; I would alert staff if you find something suspicious in a locker room."
