Virgin said in a statement Tuesday that passengers onboard Flight No. VS401 at Dubai International Airport "have temporarily disembarked the aircraft for additional security checks."
Virgin says that "this is purely as a precautionary measure as the safety of our customers and crew is our No. 1 priority."
It called the threat against the Airbus A330 as "non-credible," without elaborating.
Dubai International Airport said the flight underwent additional security checks in "close cooperation with Dubai police and the airline." It said the plane should take off at 1:45 p.m.
The security incident comes after an explosion struck a concert Monday night in Manchester, England, killing 22 people among a panicked crowd of young concertgoers.
