Seoul (CNN) About 1,600 people have been secretly filmed in motel rooms in South Korea, with the footage live-streamed online for paying customers to watch, police said Wednesday.

Two men have been arrested and another pair investigated in connection with the scandal, which involved 42 rooms in 30 accommodations in 10 cities around the country. Police said there was no indication the businesses were complicit in the scheme.

In South Korea, small hotels of the type involved in this case are generally referred to as motels or inns.

Cameras were hidden inside digital TV boxes, wall sockets and hairdryer holders and the footage was streamed online, the Cyber Investigation Department at the National Police Agency said in a statement.
