According to the Seoul Metropolitan Office of Education and Seoul Metropolitan Police Agency, one Seoul elementary school's baduk / Go (strategic board game) instructor, 'A', showed female students pornographic pictures that were stored on his laptop. 

'B', one of the students whom 'A' showed the dirty photos to, had written in her journal what 'A' did, exposing 'A's crimes when 'B's parent had read her journal entry. 

The school met with all the students who were a part of the after school baduk program and questioned the entire student body through a survey to discover whether other students were also victimized by 'A'. One other student, 'C', testified that 'A' approached her when she was sitting alone in the class room after school and showed her the lewd photos. 

The school immediately fired 'A' and reported him to the police.

The  police plan to investigate this case further and find out whether 'A' targeted more students based on student testimonies, and once their investigations confirm the crime, they will indict 'A'.
