"I have resigned on moral grounds to enable police to conduct an independent probe. There is no truth in the allegation," Mohanty told IANS after submitting his papers to chief minister Naveen Patnaik here.

His resignation comes a day after his daughter-in-law Barsa Swony Choudhury lodged a written complaint at the district headquarters town of Balasore, about 215 km from here, alleging that the minister and his family had been demanding dowry of Rs 25 lakh and a multi-utility vehicle.
