Two law enforcement sources tell the BBC's US partner CBS arrests have been made in the investigation into the actor's death.

LA police opened an investigation in May to determine why Perry, 54, had so much of the drug in his system when he died.

On Thursday, two law enforcement sources told the BBC’s US partner CBS that arrests had been made in the investigation. The news was first reported by TMZ.

Police and law enforcement officials have not publicly confirmed the reports.
