LOS ANGELES - A published report says Heath Ledger's body has been taken to a celebrity mortuary in Los Angeles where family members and friends paid their respects.

The New York Daily News says the "Brokeback Mountain'' actor's body was at the Pierce Brothers Westwood Village Memorial Park and Mortuary on Saturday, where it was taken en route Ledger's native Australia.

A call to the mortuary was not immediately returned early Sunday. The arrangements were to be private, Ledger's publicist said.

Ledger, 28, died Tuesday in his New York apartment. His body was moved from a police-barricaded funeral home in Manhattan amid a swarm of cameras and reporters Friday afternoon.

The newspaper says several people were seen entering the chapel where Ledger's coffin lay, including the actor's former girlfriend, Naomi Watts. The Daily News and et-online say members of Ledger's family also visited the mortuary.

The cause of death will not be known for at least several more days, after medical examiners complete toxicology tests. Authorities suspect a possible drug overdose. Several prescription drugs were found in the Manhattan apartment where Ledger's body was found.

Mary-Kate Olsen will not be questioned by detectives about the death of Ledger, NYPD Commissioner Ray Kelly said Sunday.

"There's no indication investigators were going to speak to Mary-Kate Olsen,'' Kelly said at a news conference.

"They determined they had all the info needed from witnesses on scene: That's the cleaning women, the masseuse.''

Kelly also said police are waiting for toxicology reports on the 28-year-old Australian actor before they decide to charge Diana Wolozin, the masseuse, for practising without a licence.

Wolozin found Ledger's lifeless body Tuesday afternoon in his Manhattan apartment, the day she had an appointment with the actor.

Police have said Wolozin made three calls to the "Full House'' actress Olsen before dialling 911 for help, then phoned Olsen a fourth time after paramedics arrived.

At some point during the calls, Olsen, who was in California, summoned her personal security guards to the apartment to help, police have said.

Olsen hasn't spoken publicly about the calls.

She has only said: "Heath was a friend. His death is a tragic loss.''

"My thoughts are with his family during this very difficult time.''
