FORT WORTH, Texas (AP) — A Texas man set fire to his mother, then went to a nearby school and held a teacher at knifepoint in a locked office before the superintendent broke down the door and helped free her, police and school officials said Monday. George James Bradley, 32, was arrested on attempted murder and aggravated assault charges after the morning incident at the Rise Academy school, Lubbock police spokesman Sgt. Jonathan Stewart said. It was not immediately clear Monday afternoon whether Bradley had an attorney.
