A class of third-year Thompson Rivers University sociology students got a surprising eyeful when an instructor inadvertently projected a pornography video onto a screen during class.

It was the second week of the second term, according to a student witness, when the instructor apparently attached the wrong flash drive to his computer.

Instead of projecting that day’s presentation onto the screen, he showed a porno film. It took less than 30 seconds for the teacher to catch it and turn it off, according to one of the students who asked that his name be withheld.

“It was something you don’t see every day. It was like, did that just happen?”

The student was reluctant to expose the instructor, saying it was clearly a mistake, it wasn’t a big deal and “he shouldn’t lose his job over it.”

“I sit with two other guys and we had a laugh. We thought it was funny,” he said. “Other than that…”

TRU’s administration was unaware of the incident until Thursday. 

Christopher Seguin, TRU’s vice president of advancement, said the university leadership became aware of the allegation through a Daily News inquiry.

“We’re informally investigating the matter,” said Seguin. “We’ll need time to understand what happened. We can’t speak to anything until we understand the nature of the event.”
