The crude explosive material detected in the cargo hold of Kingfisher flight on Sunday is suspected to have been placed while the aircraft was parked at the airport here.
According to police sources, an indication to this effect was given in the first information report submitted before a local court here on Tuesday. The flight from Bangalore arrived here at 8.05 am and the explosive wrapped in a Malayalam newspaper was spotted about 10 minutes later from the cargo section by a cleaning staff engaged by the airline, the FIR submitted in the First Class Judicial Magistrate Court here said.
The suspicion that the incident had a local connection was �reinforced as the low-intensity material � a mixture of potassium chloride, ammonia and sulphur � was wrapped in two layers of paper, first of which was a question paper of 10th standard model exam held in Kerala last year, the sources said. Since Monday evening, investigators have zoomed in on three persons, including a cracker dealer, whose statements reportedly offered some clues, the sources said.
