Matthew Perry death: Law enforcement makes arrest in connection to overdose, reports say

• An arrest was made as part of an investigation into Matthew Perry's death.
• The "Friends" actor died with ketamine in his system, a coroner found.
• Los Angeles police and the DEA are investigating how he got the excessive ketamine.

A law enforcement agency has made an arrest in connection with "Friends" actor Matthew Perry's death, according to multiple reports.

Perry died in October last year at the age of 54 . An examination from the Los Angeles County coroner's office attributed his death to "the acute effects of ketamine."

Ketamine is often used as a party drug but can also be used to treat mental health issues with doctor supervision. Perry — who had long struggled with substance use — had been using ketamine therapy before his death. But the amount the coroner's office found in his body was far greater, consistent with the amount used in general anesthesia during surgery.

Drowning and coronary artery disease were contributing factors to his death, the coroner's office said.

In March, the Los Angeles police department announced it had opened an investigation into Perry's death and was working with the Drug Enforcement Administration and the US Postal Service to determine how he'd acquired so much ketamine.

NBC News reported Thursday that one arrest was made in connection with Perry's death. TMZ reported that multiple arrests were made, and that law enforcement agencies seized computers and phones while executing search warrants.

A representative for the Los Angeles police department referred questions to the US Drug Enforcement Administration, which referred questions to the US Attorney's Office for Central California, which did not immediately respond to Business Insider's request for comment.
