Hijack threat: Max alert at Mumbai, H'bad, Chennai airports

Security at international airports in Mumbai, Hyderabad and Chennai was today put on maximum alert after the state police forces and the CISF were informed about a possible aircraft hijack attempt.

The security protocols at these civilian air facilities was increased to the level that is done on the Republic Day and the Independence Day and the Central Industrial Security Force (CISF), which guards the airports, and the police were taking special measures.

Mumbai Police last night received an e-mail, purportedly sent by a Hyderabad-based woman. She claimed she overheard six men telling each other that "all 23 people have to split from here and board flights in three cities and hijack planes".

CISF Director General O P Singh told PTI that the security apparatus at these airports has been put on "an enhanced alert and protocols have been stepped up".

"The e-mail could eventually turn out be a hoax but till investigations conclude all security drills to thwart a hijack like scenario are being carried out at the three airports," he said.

"The unidentified woman wrote in the e-mail that what she heard could be 'true or not' but she chose to inform the authorities as she felt it was her duty to do so as a citizen," a senior officer said.

The contents of the e-mail were shared by Mumbai Police with all security and intelligence agencies last night itself and a meeting of all stakeholders at these airports was subsequently convened with the input being declared specific and actionable, the officer said.

Special anti-sabotage sweeps are being carried out at the three airports since early today and security agencies, including the CISF, were carrying ourt proper passenger checks, baggage scanning, pre-emabarkation checks, secondary ladder point checking and patrols to thwart any bid to storm the airports.

The CISF has also pressed into service its sniffer dog squads and quick reaction commando teams for undertaking sanitisation drills at the airports, the officials said, even as the airlines have been asked to remain extra vigilant.

"However, there is no reason to panic and all the operations at these airports will be conducted as normally as possible so that passengers don't face any problem," a senior officer, who is part of airports security team, said.

At the Chennai airport, security has been strengthened at the domestic and international airports.

However, flight traffic is unaffected by the enhanced security measures, officials said in Chennai.

Other airports in the country have also been sanitised and officials asked to remain vigilant, the CISF DG said.

The police are probing the contents of the e-mail and trying to ascertain the identity of the sender and get in touch with the person.
