The remand, which starts today and continues until Dec 7, was granted to allow police to investigate the case under Section 12 of the Anti-Trafficking in Persons and Anti-Smuggling of Migrants Act 2007.
It is understood that the suspects, believed to be two couples, were arrested during a raid at a condominium in Bayan Lepas on Saturday.
The arrests followed a report lodged by the victim, a 25-year-old woman, who claimed she was exploited as a sex worker.
However, upon arrival, she was allegedly forced into prostitution, with foreign clients paying hundreds of ringgit per session.
Meanwhile, Southwest police chief, Assistant Commissioner Sazalee Adam, confirmed the arrests when contacted and said a press conference on the case would be held tomorrow.
