Police have made no arrests in connection with Monday's shooting that left a Utah Highway Patrol car disabled and the trooper slightly injured, police officials said Tuesday, but the investigation is continuing.

Trooper John T. Mitchell, 27, a three-year UHP veteran, was cut by flying glass and debris in the incident about 1:30 a.m. Monday in Layton. He was treated at a local hospital and discharged.According to UHP reports, Mitchell saw a late-model red Toyota Celica run a stop sign at the Hill Field and Fairfield roads intersection. He pursued the vehicle with his overhead lights on south on Fairfield Road, west on Love Lane, and then onto Fort Lane.

Shortly after turning south onto Fort Lane, Mitchell came under fire, apparently from a passenger in the car. Three or four shots were fired, UHP reported, hitting Mitchell's car in the left front tire, radiator and windshield.

The suspect vehicle fled the scene before other units from Layton, Clearfield and the Davis County sheriff's office arrived.
