A convenience store employee, who only started working there four months ago, is alleged to have filmed his female colleagues in the toilet, reported Guang Ming Daily.
One of the female colleagues found a handphone hidden in the ceiling when she went into the toilet of the shop in Puchong at about 11pm on Saturday.
She was shocked to find that the handphone's recording mode was on.
The colleague then found out that the handphone belonged to the suspect, who was arrested by the police.
There was also a video of another woman in the toilet found on the handphone.
