Officers of the Vellore district anti-drug unit searched the front and rear general coaches of the Sanghamitra Express after it arrived at Katpadi railway station.[1] The team was led by Sub-Inspector Karthik Selvam and moved after receiving information that drugs were being smuggled on that train.[1] In the rear coach, officers found a bag lying unclaimed under a seat and took possession of it after passengers in the coach said they knew nothing about it.[1] No owner of the bag was identified and no arrest was reported at the scene.[1]

On opening the bag, police found packets holding 6 kilos of ganja, the term used in Tamil Nadu for cannabis, and seized the consignment.[1] The 6-kilo figure is the police count from the packets in the single recovered bag.[1]

Police said the train runs from Danapur in Bihar to Bengaluru in Karnataka.[1] The train searched had arrived at Katpadi two days before the report.[1] Police registered a case over the seizure and were investigating further.[1]
