The home and office of Michael Jackson's doctor were raided yesterday by federal agents investigating whether the administration of a powerful sedative may have caused the singer's death.
Officials from the Drug Enforcement Administration (DEA) spent hours at Dr Conrad Murray's house and his clinic in Las Vegas looking for evidence.
It follows reports that police think the pop star was given the drug, Propofol, to help him sleep shortly before he died. It has been reported that officers are working on the theory that the powerful sedative caused his heart to stop.
Los Angeles police accompanied DEA agents as they entered Dr Murray's home in a gated community with a search warrant.
They emerged with five or six plastic containers full of documents. Dr Murray was present during the search and assisted officers who seized mobile phones and a computer hard drive, the physician's attorney said.
Meanwhile, a separate raid took place across town at the doctor's offices.
Edward Chernoff, Dr Murray's lawyer, said that investigators were looking for "medical records relating to Michael Jackson and all of his reported aliases".
The latest raids followed that on the doctor's clinic in Houston, Texas, last week.
On that occasion, agents spent two-and-a-half hours at the site, leaving with 21 documents and a "forensic image" of a computer hard drive.
