Jakarta. The Jakarta Police said on Sunday (29/01) they will question two leaders of the Islamic Defenders Front, or FPI, in an investigation over an alleged plot against the government.

Jakarta Police spokesman Sr. Comr. Raden Prabowo Argo Yuwono said Rizieq Shihab and Munarman, along with chairman of the Guardians of the Indonesian Ulema Council's Fatwas (GNPF-MUI) Bachtiar Nasir, will be questioned as witnesses on Wednesday.

The investigation will be focused on the men's participation in a number of meetings at Bung Karno University in Central Jakarta, during which a scheme had reportedly been hatched to overthrow the government, Argo said.

"We will dig deeper into the meetings to see whether they were invited, who invited them, which topics were discussed, who was in attendance, where are the minutes, and so on," Argo told reporters in Jakarta.

In the same case, police have already questioned political observer Ichsanuddin Noorsy, Confederation of Indonesian Worker's Unions (KSPI) chairman Said Iqbal and KSPI secretary general M. Rusdi.

A group of 11 high-profile activists have been named suspects for allegedly plotting against President Joko "Jokowi" Widodo and his administration and planning to hijack the peaceful prayer rally in Jakarta on Dec. 2.

Among them were also rock star Ahmad Dhani, former military generals Kivlan Zein and Adityawarman, theater director and activist Ratna Sarumpaet, former President Suharto loyalist Virza Husein, politician Eko Suryo and activists Alvinindra Al Fariz and Rachmawati Sukarnoputri – the youngest daughter of former President Sukarno.
