State toll road operator Jasa Marga reported at least Rp 400 million ($41,000) in potential losses on Friday as thousands of demonstrators blockaded the Jakarta inner city toll road, urging passage of a bill.

Thousands of heads of villages and urban wards across the country gathered in front of the House of Representatives in Central Jakarta on Friday, demanding immediate passage of a bill that would see them granted civil servant status and an increase in pay.

Agus, a village head from the Central Java district of Kendal, said 240 village officers in Kendal were not yet civil servants and only received Rp 300,000 ($31) per month. Ali Masudin, a village head from Banjarnegara, another Central Java district, said he was only paid Rp 400,000 per month.

"Ideally, our salary should be Rp 900,000," Agus told Indonesian news portal tempo.co.

In addition to blockading the road in front of the House complex, the demonstrators also spilled over into two lanes of the adjacent inner city toll road for more than two hours, resulting in traffic gridlock along Jalan Gatot Subroto and Jalan S. Parman, and surrounding areas.

Police fired tear gas and water cannons as the rally turned violent, with demonstrators rolling large rocks onto the road in an attempt to further blockade it and pushing on toll road barriers until they collapsed. Those actions followed an announcement from House Speaker Marzuki Alie, who said lawmakers could not pass the bill on Friday as the protesters were demanding.

A group of demonstrators reportedly hired infamous Jakarta gang leader Hercules to help coordinate the crowd. Police arrested 14 protesters for hurling stones at officers.

"Potential losses are estimated to reach Rp 400 million. That has yet to include barriers around toll gates damaged by the crowd. It [damage to the barriers] costs about Rp 20 million," Jasa Marga operational director Hasanuddin said on Friday, as quoted by kompas.com.
