A man was arrested from Ghutiari Sharif in South 24-Parganas on Wednesday for allegedly stealing laptops, computer peripherals, silverware and cash from three adjacent buildings in Salt Lake’s CG Block on Monday morning.

An officer of the Bidhannagar commissionerate said Javed Laskar, 25, from Jibantala in South 24-Parganas, had broken into an web development office on the ground floor of house No. 241 in CG Block.

“Eighteen monitors and computer peripherals were stolen,” said Deepak Joshi, the owner of the company that operates from the house.

Laskar then allegedly made his way to CG 243, which houses a dental clinic on the ground floor. There, too, he broke the lock on the front gate of the clinic and stole a laptop and a tablet.

Rudradeb Sanyal, the owner of the clinic, said there was a CCTV camera inside but Laskar spotted it and took away the hard disk. “The clinic was completely ransacked,” he said.

Laskar’s alleged final stop was CG 240, where he used a rod to enter the house from the rear.

Surendra Bansal, the owner of the house, said his domestic help woke him up around 4.30am after hearing some noise. “We went out and saw at least two men. One was holding a rod. Before we could realise what was going on, the men pushed my help and fled. A handbag containing Rs 19,000 is missing,” said Bansal.

Sanyal, Bansal and Joshi lodged complaints with Bidhannagar East police station on Monday.

“We scanned CCTV footage from other buildings. The men fled in an e-rickhshaw. We are trying to track other members of the gang,” said the officer.

Laskar was produced in a Salt Lake court on Wednesday and was sent to four days’ police custody.

The string of thefts have left residents of the township jittery.

“The police must increase patrolling,” said Kumar Shankar Sadhu, of the Bidhannagar Salt Lake Residents' Welfare Society.

A senior officer of Bidhannagar commissionerate said they had increased patrolling especially during early morning and dusk.
