An employee at the clinic called the emergency number 911 and told the operator: “We have somebody in either cardiac or respiratory arrest.”  The star was then rushed to Mount Sinai hospital, where the medical team is battling desperately to save her life.

It is understood that Ms Rivers’s daughter, Melissa, has been informed of her mother’s condition and is en route to her mother’s bedside.
