KITCHENER — The University of Guelph is warning people on campus to avoid one of its facilities after an explosion was reported there this morning.

A tweet posted to the U of G Alert account at 7:05 a.m. Thursday, said that equipment inside of the Gryphon Center Arena had exploded.

A spokesperson for the university says the explosion was apparently caused by a Zamboni, however the director of campus police, fire safety and emergency services, David Lee, tells CTV Kitchener that the cause of the blast is unknown.

Officials say that the damage was minor, and limited to the room in which the Zamboni was stored. The vehicle is reportedly damaged near the driver's side.

It's not clear whether the explosion is considered suspicious. There's no word yet on when the arena will reopen.

Police are on site and are aiding fire officials with their investigation, the university says. The Ontario Fire Marshal has been called as well.

The initial tweet that announced the news said there were no injuries reported.

Emergency personnel are on scene investigating, but people are being asked to avoid the building. There were bookings at the arena, Lee says, but people are being contacted to reschedule while the scene is held for the investigation.

The rest of the campus is open and classes are running.

The U of G Alert system sends email and text messages to registered users when an emergency happens on campus.
