The incident occurred in the terrorist detention room of the Mobile Brigade Command Headquarters, Kelapa Dua, Depok. The commotion occurred after the prisoners entered after Friday prayers, November 10, 2017.

The head of the Public Information Bureau of the National Police Public Relations Division, Brigadier General Rikwanto, said a number of prison facilities were damaged as a result of the incident.

According to Rikwanto, the commotion started because of a search of cell phones in the detention room. As a result, four cell phones of detainees named Juhanda, Saulihun, Kairul Anam and Jumali were found.

A number of prisoners did not accept it. One of the detainees deliberately provoked officers with provoking words and provoked other prisoners into action. Currently the situation can be subsided with the handling of picket officers.

"Members of the picket from Sat-III Pioneers took action by shooting upwards to signal a commotion and to warn the inmates. Until now the atmosphere has been controlled by the Densus picket, after that members are on standby waiting for developments," he said.
