New Delhi, Jul 21 (Agencies): In what could be an insider's job, a suspicious packet containing narcotic substance was found in the food trolley of an Air India flight at Delhi airport on Thursday.

The incident that highlighted a security breach has left all wondering how the packet reached the trolley. The Customs department is still testing and verifying the content of the packet. Prima facie, it appears to be narcotic substance.

Highly placed sources said there was a tip-off after which Customs intercepted a brown packet in the lower row of the food trolley. An Air India official claimed that at around noon, the supervisor of Sky Gourmet, an inflight catering service provider, noticed two packets, hidden beneath catering cutlery while moving the trolley from Air India flight number 440 that arrived from Chennai on July 19. A senior official confirmed to Mail Today that the packet was seized.

The trolley was loaded in Chennai. Officials claim that access to trolleys remains only with the employees and the cabin crew. Sources informed that the packet weighs close to two kilos and is suspected to have morphine. Narcotics Control Bureau officials later said it contained a mixture of morphine weighing around 1895 gm.
