Summary
A 33-year-old engineer was sentenced to 12 months' imprisonment after being convicted over covert filming in a gym changing room in Tsz Wan Shan. The court heard he secretly recorded 50 people, including 13 women, by concealing a camera in a smoke detector inside a mixed-sex changing room at an Anytime Fitness branch
Key Points
- The defendant, Wong Hung-ka (王鴻嘉), 33, described as an engineer, faced three counts of voyeurism over incidents on March 23 and March 25 to 26, 2025
- The offences took place at Shop 703B, 7/F, Tsz Wan Shan Centre, 23 Yuk Wah Street, Wong Tai Sin, at an Anytime Fitness changing room used by both men and women
- Staff were alerted to a flashing unknown object on the changing-room ceiling, found a hidden camera there, and reported the case after seeing its angle captured people changing
- After his arrest the next day, Wong said the videos were for his own viewing and that two more devices in his bag also contained footage; officers later seized two hidden cameras from his home
- The magistrate said the crime was serious and premeditated, noting the device had been hidden inside a smoke detector and the footage showed victims' private parts; Wong was jailed for 12 months
Why It Matters
The case underlines the legal and personal consequences of covert filming in places where people reasonably expect privacy, especially shared changing facilities used by the public. It also shows how venue staff detection of suspicious devices can be central to uncovering planned voyeurism offences before more victims are affected
