Seven men from Jharkhand who had allegedly planned to rob two offices in Burrabazar in two days were arrested on Kalakar Street on Thursday evening.
Officers of the detective department said they had been tipped off about the gang and shadowing the men from Burdwan station since Thursday morning.
Police said four country-made guns, 12 rounds of ammunition, two razors and leucoplast tapes were seized from them.
The men, all residents of Palamau district of Jharkhand, have been identified as Zuber Ansari, 38, Raju Kumar, 22, Rinku Paswan, 25, Zafar Aalam, 31, Anuj Singh, 32, Balram Pandey, 26 and Santosh Chauhan 27.
The police said the gang had earmarked two offices dealing in financial transactions in the Burrabazar area and planned to rob them, said the police. They planned to return to Jharkhand by train on Saturday morning.
“Last month, the gang had barged into another such office at Lohapatty in the Posta area. Their plan failed after an employee raised the alarm. The robbers’ faces, however, were caught on the CCTV cameras installed in the office,” said Pallab Kanti Ghosh, joint commissioner of police (crime). “We came to know that the men were from Jharkhand.”
As a team was preparing to leave for Jharkhand, the police were informed that the gang had again planned to carry out robberies in the city. “We learnt about their plan and the route they would take to enter the city and began tailing them from Burdwan station,” Ghosh said.
The Palamau residents had put up at two hotels at a fish market near Howrah station. “When they gathered on Kalakar Street in an attempt to rob an office, our men arrested them and seized the arms they were carrying in rucksacks,” said an officer.
