LGBTI advocacy groups in Indonesia have slammed North Jakarta police for detaining 141 men on Sunday.

The men were taken to the local police station after being rounded up at the Atlantis Gym and Sauna which has been known to be a hub for gay men.

North Jakarta Police Senior Commissioner Dwiyono alleged the venue was a place for ‘gay parties’.

‘We found a striptease arena for men … on the second floor,’ he told Netral News.

‘And on the dark third floor … there were chambers for sex parties, where we found used condoms.’

Dwiyono said local residents tipped off police.

Police said they were detained on pornography charges. The men were taken on a bus to the station and their possessions were confiscated.

They were also stripped and separated into two groups between gym clients and staff. They were left unclothed and moved between rooms for investigation.

The Advocacy Coalition for Violence Against Gender and Sexual Minority Groups said the men were still treated unlawfully by the local police by photographing the victims naked. The photos were then given to local media and spread through social media.

‘We find that act to be illegal and inhumane,’ the Coalition said in a statement.

‘The police also rejected the accompaniment of an advocate representing the Coalition for a number of victims who were rumored to be brought to the Ministry.
