Harvey Weinstein was rushed from Rikers Island, where he is being held, to Bellevue Hospital for emergency heart surgery Monday after experiencing chest pains, sources told ABC News.

The emergency comes as Weinstein, 72, is due in court this week in New York, where prosecutors had been presenting evidence to a grand jury as they work to secure a new indictment against Weinstein on sex crimes charges.

Weinstein has denied any wrongdoing and has said his sexual encounters with women were consensual.

Weinstein has appeared in court recently in a wheelchair and has asked to stay in custody at Rikers, where he has been undergoing medical care.
