London, (ANI): Michael Jackson"s personal physician has been reportedly accused of lying about the amount of powerful anaesthetic Propofol he gave to the singer before he suffered cardiac arrest. Dr Conrad Murray, who is at the centre of a manslaughter probe, had previously confessed giving low 25mg doses of the drug.

But law enforcement officials suspect the King of Pop may have been administered up to a massive 400mg on the day of his death. “We are suspicious of Dr Murray"s account of what happened. It seems very scripted," the Daily Star quoted an LA police source as saying.

Murray has previously denied any wrong doing, insisting: “I have done all I can do and have faith that truth will prevail. I didn"t kill Michael Jackson." Court papers reportedly show Jackson had "lethal levels" of propofol when he died in June.
