Indonesian police detained 51 men including several foreigners in a raid on what authorities described as a “gay spa” in Jakarta late on Friday. Some of them could face six years in prison under the pornography and prostitution laws. The arrests are the latest in a spate of high-profile police actions against gay clubs and parties in Indonesia this year that have called the country’s reputation for tolerance into question. In May, the Jakarta City Policy detained 141 men, including several foreigners for allegedly taking part in a sex party. In September, about 50 members of a hardline Muslim group, the Islamic Defender Front (FPI), barged into an apartment in the Indonesian capital to break up what they said was a gay sex party.
