Parkerson, 28, was arrested Wednesday night after he allegedly sneaked into the screened patio of a home, carrying a video camera, police said.
The homeowner's wife saw him and yelled for her husband, Pembroke Pines firefighter Ireneusz Fajkis, according to the police report.
Fajkis chased Parkerson onto his front lawn and tackled him to the ground, according to the police report.
Parkerson, of Coral Springs, was taken to Coral Springs Medical Center, where he talked to a nurse treating his wounds.
"I picked the wrong house," he reportedly said, "because a UFC
[mixed martial arts] fighter lived there and beat me up."
