Bayu Marhaenjati – The Jakarta Police have released on bail 50 students who were involved in last week's violent fuel protests, but two others remained under arrest on Monday.

The students were arrested on Thursday in a raid on the office of the Indonesian Legal Aid Foundation (YLBHI), where they were hiding.

"Fifty students can be released on bail. Investigators are preparing the administrative procedure," Jakarta Police spokesman Sr. Comr. Rikwanto said ahead of the release.

Rikwanto said police were still considering the students as suspects, and were not just letting them go, as activists had requested. "We have to follow the proper legal procedures," the spokesman said.

Police earlier released a YLBHI researcher on bail. "I don't remember his name. So, there were 53 suspects [in total], the YLBHI researcher was released earlier, then the 50 students. So now, two more remain under arrest," Rikwanto said.

He added that the two who remained under arrest were strongly believed to have been involved in the vandalizing of a car.

"Those we continue to hold in detention are Ahmad Sulyana from Satya Negara University and Syahril, a student of Tadalaku University in Palu, Central Sulawesi. They remain under arrest because of their significant involvement in setting a car ablaze. We have evidence in the form of a recording," he added.

Police also conditionally released 23 other people who were arrested in front of the House of Representatives on Friday.

"The 23 from the House have also been released. They were students, laborers, motorcycle taxi drivers, buskers and others. Their families bailed them out. They're not the ones who threw the chemical substance. We're still looking for those – we're talking to witnesses and are gathering evidence," he said.
