Vietnamese police on Monday arrested a former Vietnam Airlines employee who is suspected of having made bomb threats against flights in October, Vietnamnet reported.
Initial investigation showed that during Hanoi's millennial anniversary, Nguyen Bang Viet, a former coordinator of the carrier's flight attendants, texted a chief attendant, saying that a bomb had been planted on a flight from Hanoi to Cambodia's Siem Reap.
This prompted Vietnam Airlines to cancel the flight, tighten security and launch a search for the bomb. Authorities never found an explosive device, according to the police.
Viet, 36, was also accused of emailing another airline official and threatening to plant a bomb on a flight from Ho Chi Minh City to Sydney. No bomb was found as well, the news source reported.
The police said that, while working for Vietnam Airlines, Viet was punished for several violations.
The case is currently under investigation.
