The deceased were identified as Samila Rani, wife of Jagadish Chandra Roy and her daughter Shapla Rani, 18 of the village.
Quoting local people, Deen Mohammad, sub-inspector of Bhulli Police Station, said Shamila along with her physically challenged daughter Shapla used to live at the house as her husband lives with his second wife in a separate house.
Nani Chandra, a neighbour of Samila, said the mother and daughter had not been seen outside their home for several days.
On Monday, a field worker from a local NGO visited the house and called out to Samila but received no response.
When locals peeped through the window after a long wait they found the bodies of the mother and daughter lying on the floor.
Police were informed and recovered the decomposed bodies by breaking open the door at night, reports UNB.
Police said the woman and her daughter might have died from electrocution.
The exact cause of death will be confirmed once autopsy report is available, police said.
