CHIANG MAI, THAILAND – A 41-year-old businessman secretly installed eleven miniature cameras in women’s toilets at a shopping mall and streamed the footage wirelessly to his mobile phone before being arrested after targeted police surveillance.
Camera found under restroom sink
On 16 April, an employee in the women’s restroom of a large Chiang Mai shopping mall noticed a suspicious object under a sink. Police arrived and discovered a disguised mini-camera aimed directly at the toilet bowl.
Officers then searched all restroom facilities in the building and found a total of four such devices. Specialists from the Cyber Police examined the technology and determined that the cameras transmitted live footage via wireless signal to a receiver located outside the mall.
Trail led to luxury villa in San Phi Sua
The investigation took officers to an upscale residential area in the San Phi Sua district. There, the suspect lived in a property with an estimated market value of more than ten million baht.
On Wednesday morning, officers executed a search warrant at the villa. They arrested the businessman, whom police identified in their statement only as Chris.
Eleven cameras and digital storage seized
During the house search, officers seized a total of eleven remote-controlled surveillance cameras. They also confiscated two mobile phones and a laptop from the property.
Investigators found extensive image and video files from the mall’s toilet facilities on the devices. The suspect immediately confessed, admitting he had been installing the cameras in the shopping centre for around a month whenever he believed he was unobserved.
He told police he had hidden the devices inside air fresheners or fixed them under sinks. According to the investigation, the footage was sent in real time to his mobile phone via wireless transmission.
Instructions taken from the internet
The man told investigators he had learned how to install the cameras from online tutorial videos. He said he had purchased the necessary equipment through internet retailers.
He claimed he had not shared the recordings with anyone else. Police were examining this statement using the seized data, while a forensic team was analysing whether any of the material had been distributed.
Charged with possession of obscene material
Police charged the 41-year-old with possession of obscene material for sexual gratification. Under Thai law, he faced the prospect of significant prison sentences, and the legal proceedings were ongoing.
The case illustrated how easily accessible surveillance technology could be misused for criminal purposes. Authorities urged the public to check restroom areas for suspicious objects before use, especially under sinks, behind air fresheners and along partition walls.
Police warn of disguised spy camera technology
Investigators stressed that modern wireless technology in miniature spy cameras was almost invisible and required no local storage. Recordings could go directly to a perpetrator’s smartphone without any need to return to the device after installation.
The Cyber Police in Chiang Mai appealed to operators of public facilities to have their restrooms inspected regularly by trained staff.
“Anyone who has suspicions should file a report immediately.”
said Chiang Mai Cyber Police, in their appeal.
