Reported in the Aviation Herald:
The crew of an IndiGo Airbus A320-200, flight 6E-334 from Goa to Delhi (India), declared emergency reporting an unruly passenger on board while approaching Delhi airport. The airplane landed safely and was guided to a remote isolation bay. The airplane was surrounded by a massive deployment of security forces. The passengers were allowed to disembark more than 2 hours after landing, when the unruly passenger had been taken into custody.
An obviously already drunk male passenger, who reportedly also carried a knife, had demanded to be served liquor, which was refused by flight attendants. A fight arose, during which the passenger threatened hijack raising according alert with the flight crew, Air Traffic Control and authorities. The passenger was overcome and taken into custody by authorities after landing.
IndiGo Airlines reported, that all passengers are safe, no injuries occured.
On Oct 30th 2012 Bangalore Aviation reported, an Indian court delivered a life imprisonment sentence to the unruly passenger arguing with respect to the threatened hijack: "Even if it is presumed that he had no such intention, it must be attributed that he knew he was on board an Indigo flight carrying 160 passengers and his terrifying act could endanger the safety of the passengers as well as the aircraft in flight."
