Nearly 60,000 security personnel were deployed Thursday, nearly double the previous number, after Widodo vowed that he “won’t tolerate” more riots.
At least six people were killed, after two nights of rioting as police clashed with protesters opposed to the re-election of President Joko Widodo.
The violence has been fanned by claims from Widodo’s rival Prabowo Subianto, a retired general, that the April 17 poll was a fraud.
Indonesia’s election commission on Tuesday confirmed Widodo had beaten Subianto who has until early Friday to file a formal challenge at the Constitutional Court.
The 67-year-old has appealed for calm and said he would pursue legal channels to contest the results, as he did, unsuccessfully, against Widodo in 2014.
Election officials and analysts have discounted Subianto’s claims.
But many of his supporters appeared convinced of rampant cheating in the world’s third-biggest democracy, after India and the United States.
The streets of the capital were relatively quiet Thursday with police and military personnel keeping a close watch on the heart of the city.
Police spokesman, Dedi Prasetyo said in a statement, “We’ve detained more than 300 suspects and are now interrogating them,”
Authorities have blamed the violence on “provocateurs” that they claimed had come from outside Jakarta to stir up trouble.
