Two Ames Police officers opened fire on a driver accelerating toward the individuals around 1 a.m. Tuesday.

The officers, in separate patrol cars, noticed a vehicle driving erratically in the early morning hours Tuesday, according to a department news release. They pulled the driver over near Airport Road on South Duff Avenue.

During the stop, the driver exited, then re-entered the vehicle and drove directly toward the officers. It was at this point the officers fired their weapons.

Police said the driver was flown to a Des Moines hospital for treatment.

The incident remains under investigation by Iowa Division of Criminal Investigation, Iowa State Patrol and Ames Police.

Ames Police Cmdr. Mike Brennan declined to comment further on the incident.
