Coroner's officials have said they will not release any information on Whitney Houston's post mortem at the request of police detectives investigating the singer's death.
Captain John Kades said a post mortem had been scheduled, but that a security hold prevents him from releasing any details on its status or whether any probable cause of death has been established.
Beverly Hills Police Lieutenant Mark Rosen said that his agency may release more details about Houston's death, but it will depend on whether detectives feel comfortable releasing any information.
A member of Houston's entourage found the 48-year-old singer unresponsive in her hotel room at the Beverly Hilton Hotel, just hours before she was supposed to appear at a pre-Grammy gala. Lt Rosen said there were no signs of foul play.
A coroner's official said Houston was found in a hotel bathtub but it will take weeks to determine precisely how she died.
Assistant chief coroner Ed Winter declined to release any details about what investigators found in the room, but said coroner's officials were not ruling out any potential causes of death.He said there were no signs of trauma on Houston's body.
Meanwhile, Houston's daughter was taken by ambulance to a Los Angeles hospital and later released.
Bobbi Kristina Brown, 18, who is Houston's daughter from her marriage to singer Bobby Brown, had accompanied her mother to several pre-Grammy Awards events last week.
"At this time, we ask for privacy, especially for my daughter, Bobbi Kristina," Bobby Brown wrote in a statement released about an hour after she was transported from the hotel.
"I appreciate all of the condolences that have been directed towards my family and I at this most difficult time."
