The man, identified only as Oh, told police he put the camera in the closet of the teacher's Cheongju home "out of curiosity about a woman's private life," The Korea Times reported Wednesday.
The newspaper said the man was a salaried worker at a cosmetics company who admitted to stealing a key to the woman's house as she was visiting the company to test its new product.
Police say the teacher discovered the camera as she was cleaning up her room. The Times said Oh was nabbed after police examined the sales records of nearby camera equipment stores.
