Indonesian police have arrested 141 men attending what they called a “gay sex party” at a sauna in the capital Jakarta late on Sunday.
Police said attendees, including a Briton and a Singaporean, paid 185,000 rupiahs ($14; £10) to attend.
Homosexuality is not illegal under Indonesian law, except in conservative Aceh province.
But Jakarta police spokesman Raden Argo Yuwono said some of those detained could be charged under Indonesia’s harsh anti-pornography laws.
“There were gay people who were caught strip-teasing and masturbating in the scene,” he told BBC Indonesian.
Under the ambiguously-worded laws, putting on a live strip show for the enjoyment of the public could be construed as “pornography”.
Indonesia has witnessed increasing hostility towards its small and low-profile LGBT community.
Earlier this month, Indonesian police arrested 14 people in the city of Surabaya for allegedly holding a gay party. They could also face charges under anti-pornography laws.
The recent swiftness and intensity of the attacks against Indonesia’s lesbian, gay, community has taken its members by surprise.
Defence Minister, Ryamizard Ryacudu has described the movement for gay rights in Indonesia as a form of a modern warfare – an attempt by Western nations to undermine the country’s sovereignty. Then former communications minister Tifatul Sembiring made a call on Twitter, where he has more than one million followers, for the public to kill any gay people that they find.
