A hidden spycam ring in South Korea has been accused of secretly filming 1600 hotel room guests and live-streamed the footage online.
South Korean police have so far arrested four men accused of using the hidden cameras installed in TVs, wall sockets and hairdryer holders.
The devices were found in 42 rooms at 30 hotels across 10 South Korean cities.
Police said there was no evidence showing the businesses were aware of the privacy breach.
