Former singer Prissana Praisaeng, aka Pooky, 40, was arrested in the Ram Intra area on Monday night for alleged involvement in the trafficking of 5.2 kilogrammes of ketamine.

She was arrested with her husband Cholawit Keetatrakul, 49, on Soi Ram Intra 65 in Bang Khen district.

In the house police and narcotic suppression officials found 98.3 grammes of crystal meth, eight speed pills, 10 ecstasy pills, four grammes of ketamine and 40 grammes of marijuana, along with chemicals and equipment believed used to produce narcotics.

The arrests followed the apprehension of Taiwanese man Hung Cheng Yi, 28, with 5.17kg of ketamine at Gold Airport Hotel in Lat Krabang district near Suvarnabhumi airport. The narcotics were about to be smuggled out of the country, police said.

The suspect told police he received the drug from Pooky and her husband.

Suriya Singhakamol, deputy secretary-general of the Narcotics Control Board, said the Taiwanese suspect was a major drug dealer.
