The details surrounding the incident in Itaewon were murky Sunday, but police said the incident began with reports of shots being fired in front of a downtown hotel shortly before midnight.
Police told Stars and Stripes the unidentified soldier apparently was shooting a pellet or BB gun at passersby, who called police. Officers tried to contact the suspect near a subway station but he and another American allegedly fled in a car.
Officers grabbed a taxi cab and gave chase. They fired a shot into the air and then squeezed off three rounds at car, wounding the driver.
The Army issued a written statement saying the injured enlisted man was being treated at a U.S. hospital. It added breath tests indicated alcohol was not a factor in the incident.
