Jakarta – About 1,000 protesters angered by a student demonstrator's death after his arrest burned tires and threw stones Tuesday at a police post in the Indonesian capital, witnesses said.

The demonstrators outside Parliament in downtown Jakarta also demanded that the government revoke a 30 percent fuel price increase imposed last month.

They then headed to other parts of the city where they blocked traffic and vandalized property.

Police used a water cannon to douse the flames and disperse protesters trying to break down the main gates at Parliament, an Associated Press reporter at the scene said.

Elsewhere, protesters set fire to a police car and wandered onto the toll road to the international airport.

The main group carried a fake coffin and pictures of the late Maftuh Fauzi, a 27-year-old student from the National University who had been among 100 people protesting the fuel price rise and were arrested by police on May 24. He died last Friday from an infection, but there were conflicting reports about the cause.

The Indonesian Doctors' Association was seeking clarification from Pertamina Hospital, which said Fauzi died of HIV/AIDS. Students say he was beaten by police and died of his injuries.

Indonesia's government raised gasoline pump prices by nearly 30 percent on May 23 because of the surging cost of oil and gas on the global market. The move triggered generally peaceful protests throughout the vast Indonesian archipelago, a nation of 235 million people.
