Officials said the incident occurred early today when a CISF CCTV surveillance team deployed at the airport detected suspicious activities by a loader behind Terminal-III, just before the bags are put on the conveyor belt.
A Central Industrial Security Force spokesperson identified the loader as one Rajvir Singh working with a private company at the IGIA.
Seeing this, he said, the CCTV observer immediately alerted his colleagues on ground who then nabbed Singh.
"On physical search, nothing was recovered from Singh but during interrogation he confessed to have tried to tamper with the registered baggage of a passenger for his personal gain," the spokesperson said.
