McManus says the officer's injuries aren't thought to be life-threatening. He also says the suspect was wounded in the arm by the officer's gunshots.
Neither the names of the officer or suspect were immediately released.
Police say the incident happened after someone robbed the drive-through teller at a San Antonio Credit Union branch in southwestern San Antonio with the threat of a grenade.
