Kolkata: Police have arrested four persons on charges of smuggling heroin.
They were arrested from Lalgola in Murshidabad district on Friday.
Acting on a tip off, the police conducted a raid and arrested four of them with bags containing the narcotic substance.
It is learnt that the police were waiting at the intersection of two roads and found four of them passing. They followed them for around 500 m but the accused realised that they were being followed and as a result, they attempted to flee. However, the police chased them for another one kilometre and finally arrested them.
Cops seized a huge quantity of heroin and initiated a probe to find out from where they had acquired the same.
They suspect that they were about to pass the consignment to their counterparts, but they were arrested before they could manage to complete the task.
The investigating officers would question the arrested persons to reach the root of the case and want the kingpin to be arrested.
Police are considering the arrest to be a major breakthrough and trying to ascertain the mastermind behind the entire operation from the arrested people.
They have intensified vigil to check smuggling of narcotics substances.
