The police is conducting an investigation into the students, keeping them in custody at a police station on the charges that they distributed literature reflecting doubts about the "results of investigation" into the case of the "Cheonan" sinking in the university town and the like.

Earlier, the police took away another student of Kwangwoon University on the same charge. It pressurized the student to answer to the question as to whether there were not the Solidarity for Implementing the South-North Joint Declaration and the Youth and Students Solidarity for Implementing the June 15 Joint Declaration behind the case.

In this regard people of various circles of south Korea are becoming more critical of the police for working hard to invent a pretext for cracking down upon specified organizations after labeling them "forces behind the case", far from investigating those responsible for it.
