The dramatic 911 call made from the hotel on the night that Whitney Houston died has been released by police.
In the call, made by a Beverly Hilton security guard, it was revealed that the singer "wasn't breathing" when she was found in her bathroom of her suite in room 434 on February 11.
The unidentified man can be heard telling the emergency services operator: "Apparently, I've got a 46-year-old female found in the bathroom. I'm not sure if she fell or if she was in the bathroom with the water."
He goes on to explain that he was alerted to the emergency by a woman who was "irate and pretty much out of it" who called for help from Houston's room.
The hotel employee, who did not identify Houston in his 911 call, then informed emergency operator that he was going to the star's room.
The operator offered to stay on the line to give CPR instructions and asked whether or not anyone had tried CPR. The caller said, "No, she kept hanging up on us."
The police investigation of the I Will Always Love singers' death has been officially closed. A coroner ruled that she died from accidental drowning with the "effects of atherosclerotic heart disease and cocaine use".
A police statement read: "Based on the findings of our investigation and our review of the coroner's report, we have determined that this is not a criminal matter."
The one-minute recording has provided more insight into the circumstances surrounding her death.
Houston, 48, was found submerged face down in the bath of her hotel room on the eve of the Grammy Awards after taking cocaine.
