Matthew Perry death: Arrests made in connection with death

Several arrests have been made linked to Matthew Perry's death, including at least one doctor, according to TMZ.

Law enforcement sources told NBC News that a person had been arrested in Southern California that day.

Law enforcement sources have revealed that multiple agencies have carried out search warrants and confiscated computers, phones and other electronic devices to identify who provided Perry with the ketamine that led to him losing consciousness and subsequently drowning in his hot tub last October.

Perry was being treated with ketamine inusion therapy, with his last session taking place just a week before he died.

Perry had struggled with drug addiction for many years, and has set up a sober facility for other addicts.
