A substitute homeroom teacher in Seoul was recently terminated for allegedly masturbating in front of high school students after allegedly hitting one of them for listening to music in class.

He then proceeded to "severely beat" the student, as well as possibly another student, while the rest of the class quickly fled the room.
When confronted later about his behavior, Mr. A claimed he was merely holding on to his pants "because they were falling down," but a video recorded by one of the students and uploaded to several social networking sites forced him to admit he was being indecent.
Nonetheless, the Seoul Department of Education says it took immediate steps to sever their working relationship with Mr. A, and are currently in the process of taking legal action.
According to the paper, a sharp increase in demand for substitute teachers across the country has led schools to hire "unqualified temporary teachers" in lieu of properly trained subs.
