According to the minister, various measures, including sharing list of suspects with all concerned agencies, are done to prevent thefts at airports.
Ground handling staff are frisked while leaving airport, and they are banned from using cell phone in the air side. Besides, their photo identity cards are deposited at the airport after completion of their shifts, Sharma said.
To another query, Sharma said the Directorate General of Civil Aviation (DGCA) is in the process of framing operational guidelines for civil use of Unmanned Aircraft Systems (UAS).
"As of now, DGCA has restricted civil use of drones, UAS," he said in a separate written reply.
