Following a tip-off that teenagers were taking drugs at the house in Soi Pornprapanimit since Wednesday night, a team led by Bang Lamung superintendent Pol Colonel Chakthip Tharapanthakul raided the pool villa, arresting 16 male and 12 female teenagers.

Police also found a 250cc bottle of ketamine, drug paraphernalia, traces of white powder on a tray and two electric cigarettes.

Police determined that the teenagers had travelled from Bangkok to Pattaya City for the Wan Lai Festival and rented the pool villa for Bt7,500 per day.

Police forced the teenagers to submit to urine tests before proceeding with legal action.
