Mary-Kate Olsen called before Ledger's ambulance

The frantic moments surrounding the discovery of Heath Ledger's naked body have begun to emerge, with reports that the massage therapist who found him telephoned US celebrity Mary-Kate Olsen twice before calling an ambulance.

As initial autopsy results failed to provide a cause of the 28-year-old actor's death, police confirmed six types of prescription drugs, including a mix of anti-anxiety medication and sleeping pills, were found in his apartment.

The news came as Ledger's former partner, Michelle Williams, flew to New York from Sweden with their daughter, Matilda.

Ledger's masseuse, Diana Wolozin, phoned Olsen twice before ringing 911. In the first call, Olsen told Ms Wolozin to wait while she sent some of her security people to the apartment to find out what was going on.

After failing once more to revive Ledger, the masseuse rang Olsen a second time to say she was going to call 911 for help.

When she did, the 911 operator urged Ms Wolozin to try to revive Ledger but her efforts failed. Paramedics arrived at the same time as Olsen's security guards.

The paramedics moved Ledger to the floor and tried to revive him using a defibrillator and CPR. But he was was pronounced dead at 3.36pm local time.

It could be another 10 days before toxicology tests are able to show the cause of his death.

Police have confirmed that nearly full bottles of the anti-anxiety medications Alprazolam (Xanax), Diazepam (Valium) and Lorazepam (Ativan) were found in his apartment, along with Ambien and Zopiclone (Lunesta) sleeping pills and the sedative Temazepam (Restoril). All the drugs were prescribed to Ledger but rumours of illict drug use have begun to circulate.

In London, The Sun quoted a former Naomi Campbell employee who said they saw Ledger on a cocaine binge with the super model in 2004.

Tests on a rolled-up $US20 bill found by police in Ledger's apartment proved negative when tested for illegal drugs.

The most likely cause of death remains an accidental overdose of the anti-anxiety drugs, which can significantly slow breathing.

Combined with a heavy fluid build-up in his lungs from a bout of pneumonia, the drugs may have been too much for Ledger's weakened body.

As his body was transported to a chapel in New York, his family in Perth began making arrangements for a funeral.

Ledger's father, Kim, was last night planning to travel to the US to bring his son home.

His high school in Perth, Guildford Grammar, has offered to hold a memorial for the movie star but a spokesman said they had not yet received a response from the family.

One of the most reviled hate groups in the US has vowed to disrupt New York and Hollywood memorial services for Heath Ledger, saying the actor was a pervert who mocked God when he played a gay cowboy in Brokeback Mountain.

Film director Shekhar Kapur, who directed Ledger in The Four Feathers, may have been the last person to speak with the actor. Kapur telephoned him on Monday after arriving in New York from London.

"I last spoke to him the night before he died," Kapur said.

"He said he could not see me that night but really wanted to meet me the next day. He made me promise that I would call him in the morning and wake him up. I tried. Little did I know that his soul had already left his body."
