The workers said they protested as Riau Islands Governor Muhammad Sani had failed to meet his promise to determine wages of workers.
"So far the governor has remained silent. Decision was promised to be signed and announced on Nov 27," a leader of the protesters said.
The protested were held by police at the cross road around 500 meters from the airport. They came to the location by motorcycles and parked their vehicles in the road.
Another group of protesting workers also rallied in front of the office of the city mayor.
Meanwhile all roads to the industrial estates in the industrial island were heavily guarded by police and the military.(*)
