"He was head over heels in love with his wife. They both are very close to me. We have travelled together, too. That was long back. We have spoken on Instagram. I never thought that there is a problem. But no one can say if there is a problem between husband and wife," he told IANS.

Rohan says Karan was not a violent person. "He was not like this. On Bigg Boss, too, he never raised his voice. He never hurt anyone. It's very strange. One can't say what is going on in someone's personal life. But he has never done anything like this. Otherwise he is a gem of a person," says Rohan.

The two have worked together in "Yeh Rishta Kya Kehlata Hai".

Meanwhile, according to an earlier report in Spotboye, an FIR was lodged against Karan Mehra at Goregaon Police station on Monday night. Karan and Nisha's marriage has reportedly been on the rocks for sometime now. A fight broke out between the two on Monday night and Karan allegedly ended up hitting Nisha.
