Raju Srivastava is a fighter and will come back to be amongst all of us, the popular actor-comedian's wife Shikha Srivastava said on Thursday.

The 58-year-old comedian was admitted to the All India Institute of Medical Sciences here after he suffered a heart attack on August 10. He underwent an angioplasty the same day and has been on a ventilator since then.

Shikha said her husband is stable and the doctors are treating him well.

He is stable. Doctors are treating him well. Raju ji is a fighter and he will come back to be amongst all of us. We need your prayers and wishes, Shikha told PTI.

Srivastava, a stand-up comic who joined the BJP in 2014, was trending on Twitter on Thursday with many posts speculating about his health.

Shikha requested the media and the fans to not spread rumours as it affects the family's morale .

"My sincere request is kindly does not spread rumours. It affects our morale. We do not want negative energy, we need positivity. Please pray for his speedy recovery and he will be back soon. Doctors are giving their best and Raju ji is supporting them, He is fighting. So, kindly do not spread negativity," she added.

"He continues to be on life support and his health condition is critical. He has suffered brain damage. He has not yet gained consciousness," a source told PTI.
