“There is no reason to panic. All agencies concerned have taken the necessary precautions and security has been duly heightened after the alert,” said Patel.
Security has been stepped up across airports and passengers have been requested to arrive three hours before their flights to go through all the checks.
An additional “ladder point” security layer has also been added at certain airports to frisk passengers just before boarding the aircraft. The aviation ministry has also issued guidelines to all airlines to ask passengers to cooperate with security personnel.
