Police have said that an "open investigation" has been launched into the death of Friends star Matthew Perry.
Perry who was renowned for his role as the sarcastic Chandler Bing in the 1990s sitcom, died last October aged 54, after being found dead at his home in LA.
At the time, Perry's co stars released a statement, saying that they were "utterly devastated" over his death.
“We are all so utterly devastated by the loss of Matthew”, the cast said in this joint statement. Adding, “We were more than just cast mates. We are a family”.
Last December, the Los Angeles Police Department of Medical Examiner had ruled that Matthew Perry died from "acute effects of ketamine" and said the "manner of death is accident".
According to the LA Police Department, they have said that they are working with the Drug Enforcement Administration as part of an "open investigation" into the circumstances surrounding the death of Matthew Perry.
According to that report, Matthew Perry had been receiving "ketamine infusion therapy for depression and anxiety", with his last known treatment taking place almost a week and a half before his death.
It also said that the actor had been "reportedly clean for 19 months".
While the report could not state the "exact method of intake" in Perry's case, they did say that "The ketamine in his system at death could not be from that infusion therapy".
Last November, each of Matthew Perry's co stars from Friends, including Courteney Cox, Matt Le Blanc, Jennifer Aniston and Lisa Kudrow also paid their own tributes to Perry. Check them out here.
