A 23-year-old Waterloo man is in hospital with life-threatening injuries after what police are calling a “bizarre incident” in a parking lot at the University of Waterloo.

According to Waterloo Regional Police, they are still trying to determine the motive behind the attack and are being tight-lipped about the investigation.

Police say a 23-year-old man from Burlington has been charged with assault.

Forensic trucks and yellow police tape surround the parking lot between the Student Life Centre and Physics Activities building at the University of Waterloo.

Officers spent Sunday collecting evidence and taking pictures of the scene.

Police say the man suffered trauma to his head and was rushed to hospital by ambulance.

Waterloo Regional Police Staff Sgt. Robert Munro tells CTV News that they are not looking for any suspects and no weapons were involved in the incident.

The University of Waterloo says none of the people involving in the attack are current students at the school so they’re leaving the matter up to police to investigate.

“Right now detectives are interviewing anyone who was close by, who may have an idea of what happened.” Munro says. Police are still trying to determine if the suspects’ intent was malicious or the injuries happened as a result of misadventure.

Anyone who may have been in the area at the time of incident is urged to call police at 519-653-7700 ext. 6353 or Crimestoppers at 1-800-222-8477.
