The accused was identified as Prem Sagar, a resident of Nyay Khand area in Indirapuram of the district.
Sagar's relatives alleged he took the extreme step over the harassment by some police officials in connection with a case of his brother-in-law eloping with a girl.
"When Sagar's wife Preeti, along with her daughter, went to the nearby temple in morning, he committed suicide by hanging himself from the ceiling fan," said a senior police officer.
