Protests over the outcome of election in Indonesia were held resulting in the killing of six people and 200 were wounded.
The riots took place in central Jakarta.
Clashes between police and protesters followed an announcement that President Joko Widodo had beaten former general Prabowo Subianto.
Protests began calmly on Tuesday and turned violent after nightfall.
The protesters were carrying wooden poles, some threw firecrackers at the police and tore down public fences.
Police fired tear gas to disperse the crowd and arrested up to 100 people on suspicion of provoking riots.
Police said, the majority of protesters appeared to have come from outside Jakarta and envelopes containing money were found from some of the protestors during search.
The General Election Commission and the election supervisory agency dismissed claims of systematic cheating and rigging in the elections.
They said there was no evidence of any corruption in the election process and the polls were free and fair.
