The Cantonment railway police caught a 45-year-old labourer from Odisha trying to get out of the station and recovered 5.9 kg of marijuana concealed in a backpack on Saturday.
The personnel noticed the accused, Narahari Bariki, a resident of Banapur in Odisha, getting down the Prashanthi Express and waiting at the platform checking for exit routes without security.
Suspecting something, the personnel confronted him and checked his bag to find the drugs. An initial probe revealed that the accused had bought the drugs from peddlers from Khurda district.
