BANDUNG, INDONESIA - Indonesian prosecutors charged six people on Thursday under the country's anti-pornography law for allegedly putting on a nude dance show at a bar in the early hours of New Year's Day.

The four female dancers, the show promoter and bar manager face up to five years in jail if convicted, prosecutor Dodi Junaidi told AFP.

'They're charged under the anti-pornography law on suspicion of displaying a nude dance,' he added, without giving details.

The six suspects appeared at a closed-door trial held at the Bandung district court south of Jakarta.

The controversial anti-pornography law, which came into effect in October 2008, carries a maximum jail sentence of 15 years.

The law criminalises all works and 'bodily movements' deemed obscene and capable of violating public morality.

It has prompted protests across Indonesia, with critics saying it could threaten traditional cultures from temple statues on Hindu Bali island to penis sheaths on tribesmen in Christian and animist Papua province.

The law has been championed by Indonesia's Islamic parties and is being backed by the government of President Susilo Bambang Yudhoyono.

Muslims make up roughly 90 percent of Indonesia's 234 million population, which also contains sizeable Christian, Hindu, Buddhist and Confucian minorities.
