Dachan Seay, 30, was arrested shortly after the shooting outside of Overbrook High School on May 7.
Authorities say he was armed with a gun when he got involved in a melee that had broken out in the street.
Police say his gun went off, and the bullet ricocheted off of the ground, striking the officer in the stomach under his ballistics vest.
That officer, who has not been publicly identified, was released from the hospital last week.
