Authorities first seized 7 packets of shabu from Malaysian national Teoh Chee Keong, 41, a businessman and passenger of Philippine Airlines flight PR733 from Bangkok.
Customs examiner Beth Pableo said she ordered a thorough inspection of the Malaysian's trolley bag after noticing that it was unusually heavy. She said the shabu was found inside a secret compartment at the bottom of Teoh's bag.
Maj. Mariano Biteng of the Customs narcotics interdiction unit also found more shabu from a trolley bag of Malaysian national Richard Oh. He said the Malaysian had already left the airport, leaving his bag behind.
The bureau said the 14 kilos of narcotics have an estimated street value of P80 million.
The Philippine Drug Enforcement Agency said it is now reviewing CCTV footage at the airport to identify Oh.
