NAUGATUCK (AP) — A Connecticut police officer conducting a traffic stop opened fire on a car that drove at him and fled the scene, leading to a search for the driver that continued a day after the incident, authorities said Tuesday.

Naugatuck police said the officer stopped a car with Ohio plates at about 8 p.m. Monday on an on-ramp to Route 8. The driver drove at the officer, who fired his gun at the car.

Officials said they believe the driver was Roznovsky Machado, 24, of Waterbury, who remained at large Tuesday. Police officials said they did not know if Machado was wounded in the shooting, but believe he was the only person in the car.

Investigators found the bullet-damaged car in Waterbury on Tuesday morning.

Police did not identify the officer who opened fire on the car. Officials said he was treated for minor injuries at a hospital and discharged.

Naugatuck police are asking anyone with information on Machado's whereabouts to contact them.
