Bray Wyatt, a professional wrestler and former World Wrestling Entertainment champion, died on Thursday, the company announced. He was 36 years old.

WWE did not immediately release the location or cause of death, but said it was unexpected.

Wyatt, whose real name was Windham Rotunda, was the son of WWE Hall of Fame wrestler Mike Rotunda.

Our thoughts are with his family and we ask that everyone respect their privacy at this time,” Paul “Triple H” Levesque, WWE’s chief content officer, said on social media.

Wyatt became WWE Champion in 2017 and wrestled as multiple characters during his career, including as a member of The Wyatt Family and as a nightmarish masked alter ego called The Fiend.
