A cargo jet belonging to logistics firm UPS was forced to return 45 minutes after take-off from the airport recently for lack of mandatory custom clearances of a consignment. “One of the consignments on board did not have the mandatory Custom papers and upon inspection from the Customms, we ordered the plane to come back,” an ATC official said.

The ATC official, however, did not divulge details about the destination of the aircraft. In an earlier incident, two gates of the Mumbai International Airport were left unattended for over three hours following a tussle between CISF and Customs authorities. The tussle broke out over alleged delay in frisking of a Customs official by CISF and checking of entry and exit passes of CISF officials by Customs officials.
