A Behala resident lodged a complaint with police saying some people had gathered below his apartment early on Monday and fired shots at one of the apartment’s windows and threatened him.

Rupak Ganguly told police that at least four rounds were fired around 12.30am after some youths turned up below his apartment and started calling out his name. Immediately after this, the family said they closed all the windows and switched off the lights fearing further attack.

“Ganguly lodged the complaint in the morning and a probe has been initiated. We have drawn up a case of criminal intimidation by unknown armed persons,” said a senior officer of Behala police station.

“We are scanning all the CCTV footage of the area at night to identify whether a group of youths have been moving around late at night,” the officer said.

The police said the area comes under the jurisdiction of Ward 121 of the Calcutta Municipal Corporation and had witnessed a similar incident of firing in the open in June. Bike-borne men had fired three rounds near a market in the afternoon triggering panic among residents.

The police said the youths who opened fire at night had clearly targeted the Ganguly family.

“The idea was to threaten and not kill anyone in the family. That was successfully done,” an officer said.

“We will speak to Ganguly and others to find out why he could possibly be a target,” the officer said.
