Four men entered an office in Burrabazar, tied up two employees and robbed Rs 50 lakh on Wednesday evening. While fleeing, the gang was chased by traders and one of the goons was caught.
Police arrested the other three, too, in a raid conducted in a North 24-Parganas pocket early on Thursday.
The Rs 42.7 lakh seized from the trio was part of the money the gang had looted from the Burrabazar office, an officer said.
The police said the four youths, all in their 20s, entered the office owned by Sanjay Agarwal on the fourth floor of a building in Clive Row around 7pm.
“The firm is supposed to be trading in iron but it is into an illegal money lending business (hundi),” said an officer.
“Brandishing two bhojalis and a single-shot firearm, the gang tied up the two employees and gagged them with leucoplast,” said Pallab Kanti Ghosh, joint commissioner of police, crime.
After the gang left, the employees managed to untie and ungag themselves and alerted traders in the building.
“The four youths were racing down the stairs, chased by traders. A few traders shut the main entry-exit on the ground floor and stood guard in front of it,” said an officer of Burrabazar police station.
While one of the youths got caught by the traders, the others entered a toilet on the first floor and slipped out through a small window.
The police said the youth who was caught was named Goutam Parui. “Based on information provided by him, we raided a hideout in Bamangachhi, near Barasat, and arrested Amit Dutta, Sentu Das and Abhijit Baidya,” said an officer.
The police, however, said they suspected more people were involved in the crime.
