Wireless cameras were placed in places such as cable boxes, power outlets and hair dryers across 42 rooms from 30 hotels throughout ten cities in Yongnam and Chungchung provinces, according to a statement from the cyber bureau of South Korea's National Police Agency.
The cameras were allegedly streaming from November of last year until March 3.
Authorities only identified suspects as A, B, C, and D. Suspect A, 49, allegedly checked in to hotels in order to install what police called "spy cameras."
