Police have taken mobile phones and a computer hard drive from the home of Michael Jackson's physician Dr Conrad Murray, his spokesman has confirmed.
Dr Murray's lawyer said officials were looking for the Thriller singer's medical records as part of a manslaughter investigation into his death.
The physician, who was with Michael when he died, has not been named as a suspect.
This week's search of the doctor's Las Vegas home and offices follows a similar operation at his Houston clinic on July 22.
The investigation into his death is believed to centre around Michael's use of the sedative - Diprivan - a powerful anaesthetic also known as Propofol - which was found in his home after he died.
