POMONA — Police are hunting for a driver who fled the scene after striking a 44-year-old man on Mission Boulevard, leaving him hospitalized Sunday with grave injuries.

The collision took place just before 11 p.m. Saturday on mission Boulevard, just west of Park Avenue, Pomona police Sgt. Christian Hsu said.

Officers responding to reports of a man lying in the roadway found the man suffering from a severe head injury and determined he had been struck by a car, which fled the scene, the sergeant said.

“A witness described a 1990s, small, red sedan, possibly a Toyota Corolla, as being the vehicle that struck the pedestrian,” Hsu said. It was last seen driving east on Mission Boulevard.

The car likely has damage to its front end, and possible its windshield, police said.

Anyone with information is asked to contact Pomona police traffic investigators at 909-620-2081.
