The Drug Enforcement Agency carries out a search at Applied Pharmacy Services in Las Vegas
Drug police have searched a Las Vegas pharmacy as part of the investigation into the death of Michael Jackson.
But the Drug Enforcement Agency (DEA) would not say if the search of Applied Pharmacy Services was linked to Jackson's doctor, Conrad Murray.
Last month, police raided Dr Murray's Las Vegas home and offices as well as his clinic in Houston, Texas.
He has not been named as a suspect but court records show he is a subject in the manslaughter investigation.
On Monday, it was announced that post-mortem tests on Jackson - who died suddenly on 25 June - are complete but that results will not be announced until the police inquiry is finished.
They are expected to show that Jackson was on heavy medication when he died.
In last month's searches of Dr Murray's premises, items including mobile phones, computer hard drives and various medications were seized.
Dr Conrad Murray is a subject of the manslaughter investigation
Dr Murray's lawyer, Edward Chernoff, said after those raids that police had executed a warrant that "authorised investigators to look for medical records relating to Michael Jackson and all of his reported aliases".
Mr Chernoff said on Tuesday that he had no comment to make on the search of Applied Pharmacy Services.
Paramedics were called to Jackson's Los Angeles mansion while Dr Murray was performing CPR on the singer on the day he died, according to a recording of a 911 emergency call.
Speaking a few days later, Mr Chernoff denied that his client administered painkilling drugs that could have contributed to the singer's death.
