Chennai: Security has been stepped up at the airport here following a major security scare across airports in the country in the wake of bomb threat calls to IndiGo flights, officials said.
A 'seven-tier' security apparatus has been put in place at the Chennai airport, which has both Domestic and International terminals, even as visitors entry had been banned, they said.
While vehicles entering the airport were being checked by state police, all baggage was being thoroughly checked by personnel of Central Industrial Security Force (CISF).
Security agencies, including CISF, IB, R&AW and different wings of state police, were carrying out round the clock monitoring inside and outside the airport, officials said. Patrolling has also been intensified outside the airport, they added.
On Wednesday, there was a major security scare across several airports in the country, including Delhi, following a phone call from the US that 11 aircraft of private carrier IndiGo could be in the danger of being blown up.
