O'Malley was walking around the house with a rifle.

Sean O'Malley, the reigning UFC lightweight champion, has revealed how he was walking around a house with a rifle when he saw suspicious people.

"I saw an unfamiliar vehicle and grabbed my rifle. I went around the house. I thought about the fact that this was no longer a joke, because my wife and child were at home. I didn't know what to expect. Especially since burglars broke into Marlon Vera's house the other day. I don't want anyone to steal anything from me. They might think, "Oh, this dude's got some stuff." But it's simple. If you're willing to die trying to steal something from me, remember that I'm willing to kill to protect what's mine. This time it was all right. I just ran around the house with my loaded AR."
