Five Vietnamese nationals, including two teenagers, were detained by authorities after allegedly using suspicious passport stamps in an attempt to leave the country through Kuala Lumpur International Airport (KLIA) Terminal 2 yesterday.

In a statement today, the Malaysian Border Control and Protection Agency said the incident was detected around 10.20am by its monitoring team during a routine inspection at the KLIA2 departure hall.

“Checks on the five individuals - three adults and two teenagers - found that the exit and entry stamps in their passports were questionable in authenticity and believed to have been obtained irregularly.

“Further verification through the MyIMMS system showed no matching records of entry or exit corresponding to the passport stamps.

“Initial investigations also revealed that all the suspects had never left Malaysia and had overstayed their permitted duration,” the agency said.

It added that all five are being held for further investigation under the Immigration Act 1959/63.

The so-called “fly” syndicate refers to a scam involving falsified entry and exit stamps for foreign workers, allowing them to appear as though they had legally exited or re-entered Malaysia without being physically present.

Commenting further, the agency said it would continue to tighten control and monitoring at all major entry points to curb the use of fake or illegally obtained travel documents.

“This measure is crucial to ensure the security and integrity of the nation’s borders remain protected,” the agency added.
