Five striptease dancers and two female disc jockeys were caught red-handed while naked at a nightclub in Pekanbaru, Riau, early on Tuesday, police said.

The seven women were detained under the 2008 Anti-Pornography Law, which criminalizes performances that feature nude dancing. Under the law, those convicted could be sentenced to up to 15 years in jail.

"We caught all seven of them naked inside the club," Riau Police spokesman Sr. Comr. Syarif Pandiangan said.

He said that based on the interrogation, the two DJs, identified as A.M. and I.F., have been named suspects, while the five striptease dancers are still considered only witnesses. A.M., 22, is from Blitar, East Java, and I.F., also 22, is from Jakarta.

"We are still waiting for the results of the questioning of the other five to determine their statuses," Syarif said. He said that all suspects will be charged with the offense of publicly showing one's naked body, in breach of the 2008 law.

Police did not say whether they would charge the owner of the club for organizing such a show. The club, located on Jalan Sudirman in Pekanbaru, charged visitors Rp 75,000 ($8.30) to watch the show. Performances began every night at 9 p.m. and ran into the pre-dawn hours.

In a prior, similar case in Padang, West Sumatra, the prosecutor has demanded that two alleged striptease dancers, S.S. and N.A., be sentenced to 18 months in prison.

In an indictment read at the Padang High Court last week, the prosecutor accused the suspects of having violated the Anti-Pornography Law by dancing nude at Fellas Cafe and Restaurant in September 2011.

The suspects have claimed that they were forced to take nude pictures by one of the members of the police force in the cafe before they were arrested. The owner of the restaurant maintains that his establishment has never been a place for nude dancing.

The two suspects were detained by law enforcement on Sept. 26 and were later freed. However, on Oct. 15, they were rearrested by police.
