The Directorate of Revenue Intelligence (DRI) has seized 16 kg of heroin valued at more than Rs 80 crore at the Mumbai airport, an official said on Thursday.
A passenger was intercepted on Wednesday based on a tip-off and the search of his luggage led to the discovery of contraband.
The heroin was concealed in a cavity created inside a trolley bag, said the DRI official.
The man, a Kerala resident, was booked under the Narcotic Drugs and Psychotropic Substances (NDPS) Act and further probe was on, he said.
