The Mumbai Customs department officials arrested four passengers at the Chhatrapati Shivaji Maharaj International Airport and seized hydroponic weed (cannabis) worth Rs 13.92 crore on Friday.

The arrested passengers arrived separately in pairs via two different airlines. Pravinkumar Singh and Suraj Upadhyay arrived at the airport from Bangkok on an Air India flight, while Shivam Yadav and Mayank Dixit arrived a few minutes later on an Indigo flight, also from Bangkok.
