Delhi Post terror attack at Pathankot air force base, a high alert has been issued at Delhi's IGI airport.
As per reports on Wednesday, all the staff at the airport have been asked to be vigilant.
Reports also said that the airport's control room received a 'non-specific call' about a man heading for Germany after 'doing something big' in the national capital.
DIAL control room's call centre in Gurgaon received the call around 7 PM, following which security agencies were informed and security was ramped up, said a police official, as per PTI.
"This was not a hoax call. Such calls are technically called non-specific calls and this particular one originated from an international number. It is also suspected to be executed through the Internet," DCP (IGI Airport) DK Gupta said.
The national capital is on a high alert till January 26 and security has been already stepped up following the terror attack at Pathankot and then inputs received by the police about the presence of suspected Jaish-e-Mohammad key members here.
Security has also been beefed up at railway stations, bus terminuses, markets and around vital installations in the city.
Meanwhile, seeking to unravel how the brazen Pathankot attack was mounted, the NIA today quizzed an SP rank officer who was allegedly abducted by the
terrorists, recreated the scene of his abduction and visited the border village from where the perpetrators were believed to have sneaked into India.
On the other hand, security officials said today that the combing operations may continue for a day or two at the forward base where seven security personnel and six terrorists were killed.
Yesterday, Defence Minister Manohar Parrikar had said that the terrorists were carrying AK47s, modified Under Grenade Barrel Launcher, pistols, Swiss and
commando knives, 40-50 kg of bullets besides 3-4 dozens of magazine and mortars.
And NIA's chief Sharad Kumar on being asked about the nationality of the terrorists involved in Pathankot attack had said there was little doubt that
the accused were from Pakistan. However he had refrained from naming the terror group responsible for the attack.
