A woman using the women’s restroom at the Medicine+Science Library of the National University of Singapore (NUS) was startled when she noticed a suspicious hole in the cubicle wall she was occupying on September 2.
According to her post on Xiaohongshu, she first saw a flickering light coming from the wall around 8 p.m. local time and feared it might be a hidden camera lens.
She took a close-up photo of the object and sent it to a friend. The light disappeared briefly but then reappeared, prompting her to cover the hole with tissue. However, the flickering returned in less than a minute.
Feeling uneasy, she called the campus emergency hotline at around 8:35 p.m. and waited for security personnel, who arrived about 20 minutes later.
Upon inspection, no recording device was found—only a small white object resembling a pin inside the hole.
An NUS spokesperson later clarified that the shiny object was actually a screw from the tissue holder of the adjacent cubicle, not a hidden camera.
The hole has since been repaired by maintenance staff, and the university has offered counseling to the woman to help her cope with the traumatic incident.
