Two women from Vietnam were arrested after making a joke about a bomb at Kuala Lumpur International Airport last week. On November 22, one of the two women told staff at the airport they had bombs in their luggage as they were getting ready to board their Vietnam Airlines flight, VN Express reported.

Authorities took the two women aside and searched their luggage. No bombs were found in their baggage. False bomb threats are a violation of Malaysia’s aviation safety laws.

The two women were detained and as of November 26 were still in police custody, the Embassy of Vietnam in Malaysia confirmed. Malaysian police said it could take up to two weeks for investigations to conclude and they would update Vietnamese authorities.

Vietnam’s flagship carrier Vietnam Airlines said flights were delayed and passengers were evacuated when false threats were made. Passengers who do so are usually slapped with a year-long flight ban.
