Thai police are asking parents to lock up their daughters and not let under 18s outside after 10pm on Valentine's Day.
Police spokesman Maj-General Piya Uthayo said the national police chief was worried about youths acting 'inappropriately', taking drugs or engaging in other forms of vice on the day, hence police would be dispatched to patrol public parks, theatres,
karaoke bars, night venues, dormitories, apartments and hotels. If police find anyone under 18 outside after this time, they will be brought to police stations for their parents to pick them up, he added.
Intending also to ask night-entertainment venues not to allow the under-aged to enter their premises, with the presumed risk that they could engage in sexual activity.
Police will also punish shops that sell alcohol to under-aged persons, and will set up checkpoints to stop drunk and/or reckless riders.
Moreover, they will seek the public's cooperation, especially women, who are asked not to wear racy clothe.
