TMZ is reporting arrests have been made in actor Matthew Perry's death investigation.

TMZ says multiple law enforcement agencies executed search warrants - seizing electronic equipment - in an attempt to find the person or persons responsible for supplying Perry with ketamine, which led to the actor's drowning death after passing out in his hot tub.

The entertainment news site also claims the anesthetic drug was illegally obtained.

TMZ is reporting a doctor and several alleged dealers supplying the "Friends" actor with ketamine.
