Plano, Tex., police are investigating the death of one of the most memorable figures in pro wrestling history.

Investigators said his death appears to be accidental.

Osborne was better known as "Doink The Clown."

He wrestled for the WCW, WWF and several other organizations. Several people posted condolences on the Matt Borne (Doink The Clown) Facebook Fan Page.

On it's website, the WWE posted the following statement:

WWE is saddened by the news that Matt Osborne, aka the original Doink the Clown, has passed away. A rugged brawler in promotions like Mid-South Wrestling and World Championship Wrestling, Osborne made a major impact in WWE under the greasepaint of a prankster named Doink — one of the most enduring personas of the early ’90s.

Our deepest condolences go out to Osborne’s family, friends and fans.
