An off-duty Houston police officer who interrupted a beating and robbery has fatally shot one of the teenage suspects.
Houston police said a second suspect, a juvenile, was arrested after Sunday night's shooting.
Police said officer Carl Rodriguez was driving his own vehicle when he spotted two people attacking a person who had just walked out of a convenience store. Police said the officer ordered the suspects to stop.
One suspect, 17-year-old Oscar Gaspar, began walking toward Rodriguez and displayed a pistol.
Police spokesman John Cannon said Rodriguez, who remained in his vehicle, feared for his life and shot the teen.
Cannon said the officer took what he thought was the appropriate action to keep the beating victim from additional injury. That person wasn't seriously hurt.
