JAKARTA, Nov. 29 (Xinhua) -- The Indonesian authorities are set to deploy some 22,000 security forces across the capital during an upcoming massive demonstration.

The demonstration, organized by members of several Muslim organizations, is slated for Friday, a senior police officer said on Tuesday.

The troops and police will be tasked to guard vital state objects in the capital, National Police Headquarters Spokesperson Boy Rafly Amar said.

"We estimate the demonstration would be joined by up to 200,000 people," Boy said.

The upcoming demonstration was intended to express demands for legal enforcers to detain Jakarta Governor Basuki Tjahaja Purnama over his religious comments in September.

A series of massive demonstrations have been staged this month to protest against Basuki. The latest one was held in Nov. 4, leaving one dead, dozens injured. Three police trucks were burned down in the event.

Basuki has been declared a suspect in a blasphemy case that carries up to six years' imprisonment should he be found guilty.
