Markus Junianto Sihaloho – Anti-corruption activists installed a symbolic gallows at the National Monument (Monas) on Sunday as a macabre reminder for former Democratic Party chair Anas Urbaningrum.

Anas stepped down from his post as chairman of Indonesia's ruling party on Saturday, one day after the Corruption Eradication Commission (KPK) publicly charged him with allegedly accepting bribes.

Anas, who was once seen as a promising member of President Susilo Bambang Yudhoyono's party, famously promised to hang himself from Monas if he was found guilty of corruption.

The Anti-Corruption Youth Movement (Gepak) said they were cleaning up Monas to remind Anas of his promise.

"We are trying to help Anas keep his promise," said Toriq Mahmud, the organization's leader. "We have prepared facilities for him to realize his promise by proving a hanging pole and a rope."

The activists gave Anas a second option: publicly apologize to the people of Indonesia. "But he must bluntly reveal who was really involved in the Hambalang corruption cases," Toriq said.

Anas was charged with allegedly using bribe funds to purchase a high-end Toyota SUV. He reportedly received the funds from construction companies Adhi Karya and Wijaya Karya in exchange for the contract for the Hambalang sports center in Bogor, West Java.

He faces between four and 20 years in prison if convicted. Anas maintains his innocence and claims the accusations are part of a plot to oust him from the Democratic Party.
