The investigators also found that he does not have links with any militant organisation.

Mohla, a chartered accountant based in Dwarka held for unruly behaviour that led to the hijack scare, underwent four hours of interrogation by Delhi Police and Intelligence Bureau officials. He was sent to 14-day judicial custody on Monday.

The interrogation report — Newsline has a copy — states that Mohla had Old Monk rum before boarding the flight from Mumbai, and misbehaved with the airhostess as soon as he was in the flight.

“The joint interrogation conducted by IB, Special Branch (and) local police does not reveal any terrorist activities or connection. No affiliation with any terrorist outfit was found,” the interrogation report says.

The report says Mohla went to Panjim, Goa, on January 29 to attend an income tax and WTO conference on accountancy but could not attend the latter part of it as he fell ill. “He attended the conference on January 30 but could not attend it (conference) on January 31 due to ill-health.”

The interrogation report says that Mohla suffers from hypertension and diabetes.

In the flight on the way back home, the report says, Mohla posed as an official of the Directorate General of Civil Aviation (the apex civil aviation body) and misbehaved with the airhostess. “The airhostess is the prime witness to whatever Mohla said on the flight that led to the ‘hijack’ drama,” an official close to the investigation said. Mohla has, however, denied all charges, the official added.

Mohla’s reported ‘unruly’ behaviour on board the Indigo flight from Goa to Delhi on Sunday evening led the aircraft to make an emergency landing. The entire anti-hijacking security mechanism was on its toes during the five hours of hijack scare at IGI Airport before Mohla was picked up. The flight had 163 passengers.
