Singapore bans popular gay party
Health minister blames annual event for rise in gay HIV infections
SINGAPORE (AP) | Jun 8, 7:19 PM
Singapore has banned one of Asia’s largest annual gay-themed outdoor parties because it is "contrary to public interest,” police said on Wednesday.
The decision came a few months after a senior official in this tightly controlled Southeast Asian island nation blamed such parties for the rise in HIV infections among gays.
Hong Kong-based Fridae.com, an Internet-based network of Asian gays, applied through its Singapore subsidiary, Jungle Media, for a permit to hold its annual Nation beach party here in August.
But the application has been turned down because the "police assessment is that the event is likely to be organized as a gay party, which is contrary to public interest in general," a police statement said, without elaborating.
