Kolkata, Jun 8 (IANS): A day after West Bengal State Security advisor (SSA) and former Director General of State Police Surajit Kar Purakayastha's former wife and her mother were found dead in their residence at Salt Lake, police on Monday said that there was no foul play found in the initial investigation.

L. N. Meena, commissioner of Bidhan Nagar police commissionerate told IANS that there was normal death. He said, "No foul play was found there. The autopsy report is awaited and we have got the COVID-19 testas done on both the bodies."

A senior police official said both the bodies were sent for the post-mortem at the state run Rgkar Medical College and Hospital on Sunday and the autopsy experts said that there were no external injury marks on the bodies.

Initial investigation has said that the state's former police chief's mother-in-law was suffering from bed-sores and died of septicemia. There was infection in her body, which could be the reason for the death.

Purakayastha former wife Sharmistha 60, and her mother Papiya Dey 79 were found dead in their Salt Lake BE block residence sector one in the early hours of Sunday.

According to local sources, the mother-daughter duo was not responding to their relatives' calls for the past couple of days. When people came to sanitise the neighbourhood on Sunday morning, they did not get any response from the house. They then called the Bidhan Nagar North police station. Officials immediately rushed to the place and broke open the door. They found two of them dead in two separate rooms. Sources said that they were not keeping well since a long time.

The police officials of the Bidhan Nagar city police registered an unnatural death case (UD) with the local police station and a probe has been initiated. A senior officials of north Bidhan Nagar police station said that Shramistha also had infections.

In 2014 Shramistha, a school teacher with a degree in M.Sc in Biology with a PhD, had joined the BJP after her separation from Purakayastha. But she was not active within the party, for past few years, sources said.
