The men, and two others, posed as customers to secretly install the cameras, obtained online from overseas, in 42 rooms at 30 places around the country since last August. Police said there was no indication the businesses were complicit in the scheme.
The footage from the cameras, hidden in television boxes, sockets and hair dryer holders, were broadcast live on a website. Seoul police pledged last year to carry out regular checks of the city's 20,554 public toilets for hidden cameras.
