All the five bodies identified as those of Rajkumari (in her mid-30's), Dipesh (11), Shubham (7), Shivani (6) and Diksha (3) were fished out of the well in Begumganj, about 80 km from here, in the wee hours today, they said.
The woman's husband Chhotelal told police when he returned home from work yesterday, he could not find his wife and children. He went to a nearby well and found the body of his three-year-old daughter floating in it, following which he called police and the bodies were recovered.
Ram Singh Sahu, the woman's father, alleged Chhotelal was a drunkard and used to beat his daughter.
He said there was no way his daughter would have committed suicide.
Police have registered a case and investigations are on.
