Four persons, including a 20-year-old carpenter, were arrested on the southern outskirts in a pre-dawn raid on Monday for allegedly looting a Patuli flat earlier this month.
The cops recovered a cell phone that had been robbed along with gold ornaments and a laptop.
Those arrested have been identified as Sahinuddin Mandal, a carpenter who had worked in the flat for a few days, Banka Birla Gaji and his brother Karimollah, and Saidul Laskar. A gang member managed to give the raiding team the slip.
A gang of five armed with a pistol and a chopper had on August 8 raided the two-bedroom flat on Kendua Main Road. One of the robbers hit Ronit Dhali, a Class XII student, with the butt of the pistol, before taking away gold jewellery worth Rs 1.5 lakh, a laptop and a cell phone.
The robbers also assaulted Ronit’s 56-year-old mother Kanan Dhali when she refused to hand over the almirah keys to them.
“The mother and the son had identified Mandal. They said they had hired him for repairing and polishing some furniture. It was the first lead we got. We started following up on it and soon came to know that the carpenter was from Sonarpur,” said an investigating officer.
On the basis of the descriptions provided by the Dhalis, sleuths prepared a sketch of Mandal and handed over copies of it to their sources in Sonarpur.
“On Sunday evening we learnt about the house where Mandal had been living on rent. We raided the house early on Monday and arrested him,” the officer said.
“Mandal confessed his involvement and revealed the identity of the other members of the gang,” said Pallab Kanti Ghosh, joint commissioner of police, crime.
The three others, too, were rounded up from Sonarpur.
“The three worked under a contractor in Sonarpur. Mandal, the youngest in the gang, was the mastermind of the operation,” said Ghosh.
