Four youths in a Tata Indica introduced themselves as policemen on night patrol and robbed at gunpoint the driver and helper of a truck that had broken down at Hastings late on Monday.
All four were arrested on Tuesday and the car seized from the garage of its owner in south Calcutta.
Among those arrested was the driver of the car who had returned it to its owner after the heist.
The incident happened around 1.30am when a truck carrying jute from a godown at Burrabazar to Budge Budge broke down on St. George’s Gate Road.
“The youths spotted the truck along the road and stopped the car. They approached the driver and the helper, claiming to be cops, and demanded to see the vehicle papers,” said the joint commissioner of police (crime), Pallab Kanti Ghosh.
“As the driver got busy taking out the documents, one of the youths brandished a gun while the remaining three robbed Rs 4,000, the vehicle’s registration and consignment papers and a cell phone,” Ghosh said.
After the four had sped away, the helper went to report the matter at Hastings police station.
Police sources said the driver and the helper were able to give the registration number of the Tata Indica and that helped the cops zero in on the culprits within a few hours of the crime.
“We traced the car to a person living in south Calcutta. On checking with him, we found out that the car’s driver Guddu Singh had returned the car to the owner at night,” said an officer of Hastings police station.
The police asked the owner of the Indica to call Singh, who was arrested as soon as he turned up for work.
Guddu’s interrogation led to the arrest of the remaining three youths — Shantu Mondal, Mohammad Aftab and Mohammad Azharuddin.
The police said the robbed articles and a part of the cash had been recovered. A six-chambered improvised gun and a live cartridge along with a chopper were also seized.
Two persons were arrested from Raja Nabakrishna Street in Burtolla around 5pm on Tuesday for snatching a gold bracelet from a pedestrian at Sovabazar around 1.30pm.
Police recovered the stolen bracelet from Bijay Das and Bimal Das, who were arrested on the basis of a tip-off.
