On April 20, the Ulsan District Prosecutor's Office let a prosecutor and investigator search his house and office in Northern District of Ulsan and the house of the secretary general of the election office on charge of violating the "law on election" and seize their cell phones.

On April 14, the prosecution confiscated major materials including computer and documents in his office and on April 7 searched the office of the organizations represented by Yun Jong O after labeling it an illegal election office.

The puppet group's foolish repressive racket to bridge over the crisis caused by its election defeat would not help escape a miserable fate.
