The accused have been identified as Sanjeev (28), Devender Kumar (32), Ankur Malik (22), Anuj Tomar (27), Vijay Tomar (22) and Hans Jain (31), of which the first four worked as customs clearance agents in the airport, said DCP, IGIA, D K Gupta.
According to the police, the investigation was taken up after receiving a letter from a Delhi-based logistics company on October 29 in connection with the theft of the 8GB memory cards from a shipment which arrived from Hong Kong.
During interrogation, they told the police that the cargo agents had stolen the cards from the concerned consignment and hid them with Tomar and Jain, with plans to sell them off later and share the money.
The police have so far recovered around 26,400 memory cards from the possession of the accused. Further probe is underway, police added.
