The Kolkata Police have filed a chargesheet against two brothers, Prasun Dey and Pranay Dey, in connection with the February triple murder of three female members of their family. According to sources, police are relying heavily on the testimony of Pranay’s minor son, who was in the car when the brothers allegedly crashed into a pillar near Abhishikta More on Kolkata’s EM Bypass on February 19.

The chargesheet, submitted Thursday, invokes sections 103(1) (murder) and 109(1) (attempt to murder) of the Bharatiya Nyaya Sanhita (BNS) and comes months after a car crash culminated in the discovery of three bodies in a multi-storeyed apartment building.

According to police sources, the chargesheet shows that investigators have relied heavily on the testimony of Pranay’s minor son – while still undergoing treatment at a local hospital, the boy allegedly gave a detailed statement about an “attempted strangulation and a wrist injury”, which the police are using as a key piece of evidence, officials said.

After the car crash on February 19, Pranay allegedly made a startling confession: that the brothers had intentionally crashed the car and that three others – his wife Romi Dey, Prasun’s wife Sudeshna and his minor daughter – had died by suicide at their home in Tangra.

While an FIR initially booked some unidentified individuals for murder. However, investigation allegedly revealed that the brothers had killed the others before attempting suicide, with the police linking the entire episode to some financial losses the family suffered in their leather business.
