The New York State Department of Health is investigating the surgery which led to Joan Rivers' cardiac arrest, the Associated Press reported Thursday, Sept. 4.
The health department's spokesman James O'Hare said they are looking into "the whole matter" surrounding the 81-year-old comedienne's outpatient procedure last Thursday, Aug. 28.
Rivers stopped breathing during the minor procedure on her vocal cords, and was rushed to Mount Sinai Hospital in Manhattan. There, she was admitted in critical condition and placed in a medically induced coma. On Sunday, Aug. 31, doctors began bringing Rivers out of the coma, but the Fashion Police host still remained on life support.
The TV personality's daughter Melissa has released near-daily updates following her mother's hospitalization; the most recent one was shared on Wednesday, Sept. 3. "My mother has been moved out of intensive care and into a private room where she is being kept comfortable," Melissa said. "Thank you for your continued support."
According to the AP, O'Hare declined to discuss specifics surrounding the health department's current investigation.
E! network also confirmed to the same outlet on Thursday that Rivers' Fashion Police series will take a two-week hiatus. The popular series, which also stars Kelly Osbourne and Giuliana Rancic, will not air this Friday or the next, E! told the AP, "as we await Joan and Melissa's return in front and behind the camera." (Melissa is the weekly show's executive producer.)
