Officials raided a popular Uthai nightclub at 2.30am on Sunday after complaints it stayed open past legal hours and sold drugs. Twenty of nearly 200 patrons tested positive. The owner and related parties are being summoned, and the Ayutthaya governor will decide the action; the venue could be closed for up to five years if legal requirements are not met. For venue operators, this is a reminder that after-hours trading and drug tolerance on premises carry closure risk, and that staff and management are accountable for what happens inside.
