A red alert was issued at the Chennai Airport early Friday morning after a bomb threat call was made. Security was tightened after the police control room at the New Delhi Airport received a call that warned of an explosion.

The caller informed that a female passenger boarding a flight in Chennai bound to Saudi Arabia was carrying an explosive substance, according to a report from a leading newspaper. "Security has been beefed up in all areas of the airport including the parking lot. Passengers flying out of Chennai are requested to reach the airport well in advance to avoid any inconvenience. The heightened security measures will be in place till August 31, 2019," an official release said.

With Jammu and Kashmir being stripped of their special status after the revoking of Article 370, and the Independence Day coming up, the security has already been heightened across all airports of the country.
