The club manager, Praewprao McCulloch, was arrested and charged with violating opening hours, selling alcohol after licence hours, allowing underage people to enter an entertainment venue, selling alcohol to underage people, and allowing drugs to be used in a venue under her responsibility.
The 36 patrons were also arrested for abusing drugs and will be sent for mandatory rehabilitation.
