Two burglaries were reported in two parts of the city on Monday. One was in a housing complex at Ultadanga and the other at a Patuli home.

In the Ultadanga housing complex, occupants of the targeted flat were away celebrating Bhai Phonta. In Patuli, a man returned home to find two people inside, fiddling with his wallet and money.

They held the man at knifepoint and thrashed him with a rod but he managed to hold on to one of them trying to flee with a laptop from the house.

The Ultadanga robbery occurred inside Pratiki Abashan — a housing complex on Ultadanga Main Road in Maniktala police station’s jurisdiction.

The robbery was detected around 7pm when Swarnendu Das, the owner of the flat on the fourth floor in one of the blocks, returned with his family after celebrating Bhai Phonta at a relative’s place.

Police said Das, an IT professional, found the latch on the main door broken and one of the cupboards ransacked. “The cupboard that had gold jewellery was targeted. The family has reported that valuables worth lakhs have been stolen,” an officer of Maniktala police station said.

The housing complex does not have CCTV cameras on every floor. Cops are in the process of scanning the footage obtained from the cameras installed at the ground level, the police said.

Several outside people, including vendors, maids, and delivery people, had entered the housing complex during the time the flat had been targeted.

Cops suspect someone with insider’s information about the building’s security pattern — that guards takes a two-hour break every day between 1pm and 3pm — might be involved.

“It is apparent that someone who had specific information no one would be in the flat between 10am and 7pm and that the building would be unmanned between 1pm and 3pm was involved,” an officer in Lalbazar said. “With such specific information, the role of an insider cannot be ruled out.

The floor where the burglary took place has two more flats, one of which had residents throughout the day.

The other robbery was reported at Patuli police station on Monday. Two men had broken inside a house in Baghajatin Colony while its occupant was away.

Subhankar Mukherjee, 25, had returned to his rented apartment in Baghajatin Colony around 3.30pm.

He has told cops that he found the collapsible gate in the front broken and two men inside holding his wallet and Rs10,000 in their hands. One of the men had Mukherjee’s laptop bag in his hand and was trying to flee through the door at the back on seeing Mukherjee.

“One of them took out a knife and the other attacked him with a rod before slipping out of the rear door. Mukherjee started shouting and gave chase and managed to catch the man who had his laptop bag with the help of a youth,” an officer said.

The captured man has identified himself as Deb Kumar Haldar, a resident of Narendrapur, the police said.

Haldar will be produced in court on Tuesday.
