Police officials said the incident happened at 4.45 pm.
"When the flight was on the runway, a loader was seen jumping from the baggage section of the plane. The pilot was immediately alerted about aborting the take-off," police officials said quoting eye-witness.
Airport authorities were yet to file a complaint against the loader who was not yet identified.
"The flight was allowed to take off after a thorough security check as the behaviour of the loader was found to be suspicious," police said.
