One student was injured and another was taken into police custody after shots were fired Friday in an altercation during a fire drill at a high school in Winston-Salem, the authorities said. Gunfire was reported at 2:30 p.m. at Carver High School as students began to walk back inside the school buildings at the end of a planned fire drill, said Chief Barry Rountree of the Winston-Salem Police Department. A student was wounded, but the injuries were not life threatening. No one else was hurt during the altercation between the students, both of whom were enrolled at Carver, Chief Rountree said. "We had a school resource officer who was in close proximity, and he immediately took the shooter into custody," he said.
