Irawaty Wardany, Jakarta – Police have not arrested any members of a hardline Islamic group who stormed a human rights training session for transgender individuals, but instead plan to summon the victims.

"We are handling this matter carefully to avoid social tension," Depok Police detective chief Comr. Ade Rahmat said Saturday, adding that police had questioned six of the organizers of the training program.

"We plan to summon the program leader on Monday," Ade said. "We know the Muslim fundamentalist movement in Depok is strong. [Friday's] incident was instigated by the Islam Defenders Front [FPI]," he said.

The National Commission of Human Rights (Komnas HAM) was conducting a three-day program to train transgender groups on human rights at a Depok hotel when dozens of FPI members broke into the training room after a coffee break, destroyed some property and assaulted participants.

The FPI members attacked a participant from the Indonesian Legal Aid Foundation who was to speak at the event, while other participants suffered injuries from broken glass, according to participating organization Arus Pelangi.

The FPI has a long, mostly unpunished criminal record of usually violent raids, including raids on nightspots in Jakarta, usually conducted during the fasting month of Ramadhan.

The hardliners were also involved in unconstitutional assaults to force the closure of houses of worships belonging to religious minorities in some areas across the country.

The FPI was also involved in an incident with a group from the National Alliance for the Freedom of Religion and Faith (AKKBB) in June 2008 in the National Monument (Monas) Park.

"We were also threatened by public order officers who came to the hotel at 9:30 p.m. and told us to stop the training," organizer Hesty Armiwulan from Komnas HAM said.

Hesty added the public order commander, Sariyo had said organizers did not have permission from Depok authorities to hold the meeting. "But I insisted on continuing since we did not commit any crime or create public disturbances during the event," she said.

However, Hesty continued, at 10 p.m. electricity in the room was suddenly switched off, but participants continued even with dimmed lights and without a microphone.

"The police officers who were guarding the premises following the [illegal] FPI incident in the morning did not seem to bother to stop them," Hesty said.
