San Antonio police arrested Karl Rogers, 21, and Adrian Sanchez, 22, in connection with an attempted burglary at BTT Texas in San Antonio, TX.
Investigators said Rogers broke into the gym through a garage door during the overnight hours, but was confronted by MMA fighters who were still inside training.
"We're just kind of sitting down, drinking water, talking about what's going on, and we start to hear pounding on this door," said Caleb Murphee, MMA fighter.
Murphee said he and another fighter grabbed some weights to throw at the would-be burglar, but Rogers fled when he saw the fighters.
Officers arrived and found a getaway driver, later identified as Sanchez, trying to hide in the parking lot behind a shopping center.
The officer scaled a fence and found Rogers rounding a corner, carrying a hatchet.
The officer convinced Rogers to drop the weapon and took him into custody along with Sanchez, police investigators said.
Murphee said he's glad no one was hurt, but felt confident he could defend himself. "If he would have tried to rough me up or something, yeah, I definitely would have defended myself. I feel confident I would have come out on top," Murphee said.
