Four people were arrested from north Kolkata's Sinthi area following the seizure of semi-finished country-made firearms along with high-quality fake Indian currency notes (FICN) with a face value of Rs 50,000 from their possession, police said on Thursday.
Acting on a tip-off, a Special Task Force (STF) unit of Kolkata Police apprehended the four in Sinthi More area and seized from their possession one improvised carbine with a dual magazine, 10 pieces of semi-finished pistol body and the FICN on Wednesday night, he added.
"They are part of a notorious gang from Munger (in Bihar). We have arrested them and questioned them to find out to whom they were planning to hand over these materials," the police officer said.
When produced before a local court, the four were sent to 14 days of police custody.
