An Anne Arundel County police officer shot at a car Tuesday morning as it charged toward him and then struck him, but police said they do not know if a bullet injured anyone.

Lt. James Fredericks said police were called to the 2000 block of Tea Island Court in Odenton around 4 a.m. for reports of two men going through vehicles. An officer saw a Kia Sportage in the road and as it came toward him, he thought it was going to run him down, according to Fredericks. He fired at the SUV, and was knocked to the ground by the vehicle, which continued into a nearby dead-end, where two people got out and ran, Fredericks said.

Other officers apprehended one person, who was not struck by the bullet, Fredericks said. The search for a second person was continuing.

The officer who was struck was treated at Baltimore Washington Medical Center and released. He is 33 years old and has been with the department for 9 1/2 years. Under department rules, he was placed on administrative leave, and has not been publicly named yet.

Anyone with information is asked to contact Detective Jason DiPietro at 410-222-3415, or Metro CrimeStoppers at 1-866-7LOCKUP.
