Five people, including the assistant of Matthew Perry, have been arrested in connection to the actor's fatal drug overdose.
Perry's assistant, Kenneth Iwamasa, pleaded guilty to conspiracy to distribute ketamine, causing death, according to the Department of Justice.
United States Attorney for the Central District of California Martin Estrada made the announcement on Thursday.
“Following Mr. Perry's death in October of last year, law enforcement, my office and our partners represented on this stage began an in-depth, wide-ranging investigation,” he said.
“That investigation has revealed a broad underground criminal network responsible for distributing large quantities of ketamine to Mr. Perry and others.”
