She also denied there were any illicit relations between her husband and Anita Durrani, a dental surgeon, which the police said was one of the reasons for the twin murder.

"Even after all this, I can say it has nothing to do with this. There is no such thing," she told a news channel.

Coming out in strong defence of her husband, Nupur said, "With all my conviction I can say it (Rajesh killing Arushi) can't be the way it is suggested (by the police). He was a doting father. It is doubly untrue.

"In fact, I used to feel that I had done something good in the past to be part of such a wonderful family. I have faith in the legal system and I have faith in God," she said.

Nupur, who is also a dentist, said she cannot believe that her husband could be behind the murders. "It is not possible, just not possible. The killer is out there somewhere. We will have to fight it out in the court. The truth is there. The truth has to come out."
