Over three kilograms of charas was seized in the Chamba district after a motorcycle-borne man, who was allegedly carrying the contraband, sped away after throwing his bag when signalled to stop at a check post, an official said Sunday.

The State Narcotics Crime Control Unit (SNCCU) official said the unit had got a tip-off that a Kilod village resident would be going to Pathankot on an 'unnumbered' motorcycle with a bag containing charas.
