London, August 15 : An anaesthetic believed to have killed King of Pop Michael Jackson reportedly came from a pharmacy in Las Vegas, which was raided this week.

The `Thriller' hitmaker's personal physician, Dr. Conrad Murray, bought the drug propofol, which is usually used to render patients unconscious for major operations, from the drug store on May 12.

According to the Mirror, the doctor gave doses of the sedative to the singer in the hours before he died on June 25.

Dr. Murray became the focus of a manslaughter probe after Jackson's death.

The newspaper report further reveals that Drug Enforcement Administration agents and police served a search warrant on the pharmacy on Tuesday.

The authorities were looking for credit card receipts and other documents related to the purchase.

After a 90-minute search, they seized only paperwork from the pharmacy. (ANI)
