New York - Police investigators searched a pharmacy in Las Vegas on Tuesday as part of their probe of Michael Jackson's private physician, Conrad Murray, the internet entertainment news site tmz. com reported.

Drug experts intended to confiscate computer data and records that would give details about the pattern of Murray's written prescriptions for patients.

The cardiologist is suspected of giving a highly dangerous anaesthetic, Propofol, to the King of Pop to help him sleep on the night before his untimely death on June 25.

He is being investigated on suspicion of manslaughter. In July, police searched Murray's home and practice.(dpa)
