A case under the Anti-Dowry Act has been registered against Union Human Resources Minister Arjun Singh [Images], his wife Saroj Singh, daughter Beena Singh, son Abhimanyu Singh, grandson Abhijeet Singh and two others at a police station in Moradabad late on Sunday, the police said.

The minister has denied his involvement.

The case has been registered on the direction of Additional Chief Judicial Magistrate, Chandausi, on a complaint by Madhvendra Singh, the father of the Union minister's granddaughter-in-law Priyanka Singh, Moradabad district police chief Prem Prakash told PTI.

The court had ordered the registration of the case on July 27 but the FIR was registered at Chandausi Kotwali police station Sunday, he said.

Madhvendra Singh has alleged that his daughter's in-laws had been demanding a Mercedes car and a flat from him and his daughter was being tortured when their demand was not met, Prakash said.

Singh, who normally avoids the media, was quick to deny his involvement.

"I have nothing to do with the family," Singh said. 

The minister is exploring all legal options.
