Sukarno then planned a three-day series of meetings to restore his authority. The first, on 10 March, involved the leaders of political parties. He managed to persuade them to sign a declaration warning against the undermining of presidential authority by student demonstrations. The second stage was a cabinet meeting planned for 11 March. However, as this meeting was underway, word reached Sukarno that unidentified troops were surrounding the palace. Sukarno left the palace in haste for Bogor, where later that night, he signed the Supersemar document transferring authority to restore order to Major General Suharto. Suharto acted quickly. One 12 March he banned the PKI. The same day, there was a "show of force" by the Army in the streets of Jakarta, which was watched by cheering crowds. On 18 March, Subandrio and 14 other ministers were arrested., including the third deputy prime minister Chairul Saleh. That night, the radio announced that the ministers were in "protective custody".
