Five people have been charged in the death of former Friends star Matthew Perry.
The 54-year-old was found dead in a hot tub at his Los Angeles home in October.
Officials later determined that the actor suffered a fatal ketamine overdose.
A licensed physician and an alleged drug dealer were arrested on Thursday.
They are charged in an 18-count superseding indictment with distributing ketamine to Perry during the final weeks of his life.
Three other individuals, including a second doctor and Perry’s assistant, have already pleaded guilty to charges.
