A Fontana police officer was in stable condition Sunday as authorities continued to search for the men who shot him.
The 27-year-old officer, whose name was not released, was shot after he stopped a car for a traffic violation Saturday night in north Fontana.
The four-year veteran was shot several times in the torso, police said. The officer fired back, but police do not know if he hit the men.
Investigators said the officer apparently was unaware that two men with pistols had carjacked the vehicle in Rancho Cucamonga a day earlier.
Police were searching for two or three men in their early 20s with shaved heads who ran from the car after the shooting.
The officer underwent surgery for his wounds Saturday night.
