Umashankar was a motor mechanic, they said, adding his second daughter is the only surviving member of the family. She was not here when the tragedy struck.
"She studies in Varanasi. Her wedding was scheduled in November this year," a senior official said.
According to locals, the family had been living in the house for almost three generations.
