The men, aged between 19 and 60, were picked up around 8pm on Friday in a surprise raid involving Kuala Lumpur police, Kuala Lumpur City Hall and the Federal Territories Islamic Religious Department (Jawi).
Of those detained, 17 were identified as civil servants, including a surgeon, a deputy public prosecutor, an administrative and diplomatic officer, a teacher and several enforcement officers.
Kuala Lumpur deputy police chief Mohd Azani Omar said intelligence and surveillance on the two-storey premises along Jalan Raja Laut had been conducted for two weeks following public complaints.
“Investigations revealed that immoral activities were allegedly taking place on the premises involving male patrons,” he said at the scene.
The centre, which operated under the guise of a health and wellness facility equipped with a gym, sauna, spa, swimming pool and designated rest areas catering specifically for men, was believed to have been running for the past eight months, Azani said.
