According to ABC News, the doctor who performed Joan Rivers’ endoscopy, which led to her cardiac arrest, has stepped down from Yorkville Endoscopy.

Dr. Lawrence Cohen was the clinic’s medical director and gastroenterologist, and in a statement to ABC News, the clinic said that Cohen “is not currently performing procedures at Yorkville Endoscopy; nor is he currently serving as medical director.”

According to the New York Times, an unauthorized ear, nose and throat specialist was present in the operating room during Rivers’ procedure. The unauthorized specialist was reportedly brought in by Dr. Cohen, who allowed the specialist to examine River’s voice box both before and after the endoscopy.

Yorkville Endoscopy did not immediately reply to EW’s request for comment.
