Sinha was admitted to Kokilaben Hospital in July last year after he complained of breathlessness due to some paint work at his residence. He underwent bypass surgery as blockages were discovered in his coronary arteries.
"He is fine. He is in the hospital for routine check up because of the bypass surgery he underwent last year. We prefer not to talk about it," Sinha's son Luv told PTI.
When asked will he be admitted, Luv said, "This kind of check up takes time. The doctors will be in a better position to talk about it". Doctors at the hospital remained unavailable for comment. The actor, who made his Bollywood debut in 1969 with 'Sajan', is currently BJP MP from Patna Sahib in Bihar.
