A D.C. police officer shot at a man who pointed a gun, police said, but no one was injured during the incident.

About 9:10 p.m. Wednesday, officers were informed that there was a man with a gun in the 700 block of Tewkesbury Place NW, which is not far from Coolidge High School. When police got to the area, they tried to stop 29-year-old Rouchell Chesson, who they say ran and pointed a gun at an officer. That officer then fired his or her weapon, but Chesson wasn't hit, police said.

Chesson, of Northwest D.C., was arrested on charges of assault with a dangerous weapon, felony assault on a police officer, carrying a pistol and possession of an unregistered firearm, according to police spokesman Officer Araz Alali.

Police are not identifying the officer who shot at Chesson and are conducting an internal investigation into the incident.
