Two high school teachers were arrested for alleged sexual harassment of nearly 80 students in Yeoju, Gyeonggi Province, police said Wednesday.

The two men were accused of touching students' buttocks during physical education classes or on other occasions. Some of the alleged victims reported it to a teacher who asked for a police investigation in mid-June.

An alleged victim told police the teachers "used to greet students with touching their buttocks."

One of the teachers admitted to the controversial act, but denied it was done with malicious intent. The other teacher strongly denies the accusation.
