The 29-year-old man, who had confronted Orange County sheriff's deputies in the past, underwent surgery after suffering what Sheriff Jerry Demings described as life-threatening injuries.
Demings did not name him or the female wrestler, who he said was not at the WWE's Orlando training center at the time of the shooting.
According to the Orange County sheriff, two plainclothes officers responded around 1:30 p.m. to a call from a manager at the Performance Center that the man had come in and created "a commotion." At the time, WWE staff told authorities the man "had some type of knife."
So when the two officers arrived, they drew their weapons, fearful the man might go after them, police said.
And while it wasn't clear if he was armed, the man did charge at one of the officers in the facility's parking lot.
"And so the deputy retreats," Demings said. The officer "was running backward trying to create distance between he and the subject, and ultimately the subject closes within just a few feet of him. And he fired the shot."
Cpl. Steve Wahl was the officer who fired that shot, according to Deming.
The man he shot has an extensive history of run-ins with law enforcement, including arrests for robbery and battery against a law enforcement officer and an August 4 arrest for trespassing. The sheriff said this past includes having previously confronted deputies with "some type of chain."
Paul Levesque, a longtime WWE wrestler known as "Triple H," now executive president with the company, tweeted that "a deranged individual with no WWE affiliation, who had a court order prohibiting him from being on WWE property, was involved in (the incident)." The man had not yet been served with the order, according to authorities.
Demings confirmed the man had undergone a mental health evaluation under what's known as the Baker Act
, which allows for voluntary admissions and involuntary examinations.
