Bhola, allegedly stabbed his wife Aarti several times with a kitchen knife in the Mall area, after a brief altercation.
He was arrested on the basis of a complaint filed by Aarti's family, under the dowry prohibition law, police said.
Superintendent of Police (Rural) Saumitra Yadav said that the accused married Aarti, a resident of Hardoi, a year back and had been harassing her over dowry since then.
The woman had complained to her kin about her being beaten frequently over dowry, but the matter was settled between the families, police said. A probe is being conducted to collect evidence against Bhola for the allegation. He has also been interrogated after Aarti's family lodged the complaint.
Dowry deaths are still rampant in many parts of India where young brides are harassed and tortured for the same.
