Season 1 scholar Yvan Lambatan was arrested in a drug buy-bust operation in Baguio City Tuesday night.
A sachet containing methamphetamine hydrochloride or "shabu" weighing 0.3 grams was recovered when Lambatan handed it to operatives of Philippine Drug Enforcement Agency-CAR.
The singer, however, said he wasn't selling the illegal drugs.
"Actually, hindi talaga ako nagse-sell. Tinuro lang nila ako pero hindi talaga ako nagtutulak. Iniabot lang sa akin para iabot sa tao, yun lang. Ngayon ako napagbibintangan," Lambatan said.
A criminal case against Lambatan has been filed by the city prosecutor.
Lambatan was part of the first season of the hit reality show "Pinoy Dream Academy' on ABS-CBN.
Yeng Constantino, a singer-songwriter from Rodriguez, Rizal, emerged the winner in the contest.
