A pinhole camera was found inside a toilet for the handicapped in Nanyang Technological University (NTU).

The camera was supposedly hidden inside a plastic hook that was mounted on the door, Lianhe Wanbao reported yesterday.

The police told The Straits Times yesterday they received "a call for assistance on a case of insulting the modesty of women in Nanyang Drive" at 5.03pm on Thursday.

ST understands that the camera was found by a female printing service contractor.

There was an SD card in the camera, but it is unclear whether there were any videos or pictures in it.

An NTU spokesman told ST a suspected pinhole camera was found inside a toilet for the handicapped at Basement 1 of the Humanities and Social Sciences Building on Thursday afternoon. He added that the university has stepped up security patrols in the area.

A cleaner at the school told Lianhe Wanbao that a woman told him on Thursday that she noticed a camera in the toilet.

She was said to have told him she spotted a hook on the toilet door which had not been there before.

The woman, who was not named, told Lianhe Wanbao the position of the hook, on which an air freshener pack hung, was unusual - at the same level as the toilet bowl.

Ms Amanda Yang, 21, a second-year NTU undergraduate studying English, told ST that she saw a video her friend had uploaded on Instagram showing the police investigating the case.

"The toilet for the handicapped is used pretty frequently by the girls because there are only four stalls in the ladies' toilet, so I guess we are all rather worried at the moment," she said.

Police investigations are ongoing.
