The victim was identified by police as Sarthak Sarkar, a software engineer employed at a company in Salt Lake's Sector V. His body was recovered on Saturday night from a rented flat in Garia, where he lived with his girlfriend, Sanchalika Basu.

According to police, a disturbance broke out between the couple on Saturday night, during which Basu allegedly struck Sarkar on the shoulder with a sharp weapon. Neighbours, alerted by screams, rushed to the flat and took the injured man to a hospital, where doctors declared him dead. The allegation has not been proven in court.

Police said they arrested Basu after an initial investigation and subsequently arrested her mother, Moumita Basu, on suspicion of involvement in the killing. Investigators said they suspect the mother may also be connected to the killing and plan to interrogate both arrested persons in custody.

Sarkar, a native of Barasat in North 24 Parganas district, had rented the Garia flat with Basu, who police said studied at Techno India Institute.

Police said the motive for the disturbance remains unclear. They are investigating whether the attack stemmed solely from the altercation or whether other reasons were involved, and what role, if any, the mother played.
