Police arrested four Meghalaya residents, including a woman, after 15 kilos of cannabis was seized from their vehicle in Jalpaiguri on Monday night.

Police sources said they had information that an illegal consignment of narcotics would be smuggled to Bihar from the northeast. Accordingly, a team of Kotwali police station intercepted a car on NH27 at Gosala More, on the outskirts of Jalpaiguri town, around 9pm.

As the policemen searched the vehicle, they found 15 kilos of cannabis concealed in it.

“The vehicle that has been seized bore a registration number of Meghalaya. During preliminary probe, it has been found that the cannabis was loaded somewhere in Assam and was supposed to be smuggled to Bihar. We are trying to find out whether the arrested quartet, all residents of Meghalaya, are mere carriers or associated with a drug smuggling racket,” said a police officer.

The estimated price of the seized consignment is Rs 75,000, the police sources said.

On Tuesday, the quartet — Sanjib Roy, Jagmohan Roy, Vicky Kunar and Bina Ranglihat — were produced at a local court and remanded in judicial custody for 14 days.

In another incident, a suspected smuggler was apprehended by 174 battalion of the Border Security Force at Hamjapur border outpost in South Dinajpur district on Monday.

Aynul Miya, a resident of Banspatharia in the district, was trying to cross the India-Bangladesh border with 124 bottles of cough syrup when the BSF men intercepted him.

The BSF carried out raids in different locations across north Bengal on Monday and Tuesday and seized a number of items including cattle, cannabis and cough syrup worth Rs 3.08 lakh, said sources.
