Mesa police say an officer and a man were hospitalized after the man's car struck the officer during a traffic stop and that the officer then shot the man.
Police say the incident occurred early Saturday morning when police pulled over a man who was suspected of being impaired.
Police Department spokesman Steve Berry said the driver didn't follow officers' instructions and then reversed his car, striking one of the officers and a police car.
Berry said the officer dropped a stun gun before drawing his gun and shooting the driver.
The officer suffered what the Mesa Police Association called a minor leg injury. No information was immediately available on the suspect's injuries and no identities were released.
