Now feeling certain that Jungjong was sufficiently estranged from Jo, Hong Kyung-ju secretly entered the palace to warn King Jungjong that the court was filled with Jo's supporters and that no one could dare oppose him openly. When Jo petitioned Jungjong to revoke special privileges of people who falsely contributed to 1506 coup, Jungjong's suspicion was further heightened. Jungjong dispatched a secret letter to Hong Kyung-ju, expressing his fear that Jo Gwang-jo would next go on to question legitimacy of the coup and then turn against him. Jungjong instructed Hungu leaders to kill Jo Gwang-jo and then inform him. On November 15, 1519, Hungu leaders entered the palace secretly at night to bypass Royal Secretariat and present to the king written charges against Jo: he and his supporters deceived the king and put the state in disorder by forming a clique and abusing their positions to promote their supporters while excluding their opponents. Inspector Jo Gwang-jo, Justice Minister Kim Jung, and six others were immediately arrested, and they were about to be killed extrajudicially without trial or even investigation. The whole event had appearance of coup d'état except that it was sanctioned by the king.
