Subsequently, two more persons went inside but they too did not come out following which the house owner's wife climbed down into the newly-built septic tank, he said.
When none of them came out, a child from the neighbourhood alerted the villagers who rushed to the spot, he said.
The deceased were identified as Savitri (45), Badu Tam (60), Paramjeet Paikra (19), Ramjeevan Ram (35) and Ishwar Sai (40), he said.
Prime facie, it is suspected that they died of suffocation, he said. However, the exact cause of their deaths will be known in the autopsy report, he added.
A case was registered in connection with the incident, he said.
