Washington, Sept 29: Dr. Conrad Murray asked to go back to Michael Jackson's house "to get rid of a cream that the world should never see" as the singer lay dead, a court heard on Wednesday.

The medic - who is currently on trial for the involuntary manslaughter of the 'Thriller' singer, who died from acute Propofol intoxication in June 2009 - allegedly panicked after Michael was pronounced dead in hospital and begged to be taken back to the Los Angeles property where he died, reports Contactmusic.

However, Michael's personal assistant Michael Amir Williams refused to let him and asked security to place the house on "lockdown" so he couldn't get back into the mansion.

Williams also told the Los Angeles courtroom that he lied to Murray and told him the keys to his car had been taken by the police as Michael's personal physician insisted that he be taken back to the house.

Murray then allegedly asked to be taken "to get food" but Williams once again refused him.

The court was also played the panicked voicemail that Murray left on Williams' phone after finding a lifeless Michael.

When he called Murray back, two minutes later, he claims he was told Michael had had a "bad reaction" and to "get somebody here immediately" but was not asked to call 911.

When the assistant arrived at Michael's mansion he said he saw his body being brought down the stairs on a gurney and Murray seemed "frantic". (ANI)
