Sgt. Warren Mitchell on Wednesday confirmed the arrest of Jason Keith Yarborough. Yarborough has been charged with aggravated assault on a public servant using a deadly weapon.
Sr. Cpl. Officer Matthew Wagner was shot twice early Tuesday but is expected to recover.
Wagner and another off-duty officer were questioning a man in a vehicle when a struggle broke out and a suspect began shooting. The gunman ran away.
Police say Yarborough's fingerprints were on the magazine of a gun dropped at the scene.
Further details on Yarborough, who was arrested late Tuesday and remains in custody, were not immediately available.
