After spending two hours searching the Sheridan College Institute of Technology and Advanced Learning campus in Oakville, police concluded that the professor had probably seen a man carrying a video tripod, the Toronto Star reported.
Robert Turner, the Sheridan president, said that officials watched a surveillance video of the mystery man and came to the same conclusion as the person who reported him. The man was wearing camouflage clothing.
Erica Eng a 22-year-old journalism student, said that she spent two hours locked in a classroom with five other students sheltering under a desk. Students watched reruns of "Family Guy" to relieve boredom and tension.
During the search, police detained a man who matched the description of the person they were looking for. He was released after brief questioning.
