Police are searching for a hit-and-run driver Thursday morning who, according to witnesses, returned to the scene of a crash in downtown Los Angeles that left a pedestrian critically injured before fleeing a second time.

A man was in a marked crosswalk at the intersection of East Sixth Street and Towne Avenue in Skid Row about 12:20 a.m. when he was struck by a dark-colored Cadillac CTS, Los Angeles Police Department Detective Felix Padilla said.

The driver did not stop and witnesses watched as it continued eastbound on Sixth Street, Padilla said.

Within minutes, the hit-and-run vehicle returned to the scene and passed the fallen victim, according to an LAPD news release. One of the witnesses told the driver to stay, Padilla said, asking the motorist, “Why did you hit him?”

The driver ignored the person and took off northbound on Stanford Avenue, Padilla said.

One witness followed the Cadillac on a motor scooter, getting the Cadillac's license plate, 5YTE203. The vehicle was a four-door black Cadillac CTS, police said.

The victim, described by LAPD as a Hispanic man in his 50s, suffered severe head and body trauma and was in critical condition following the crash. He underwent surgery at Los Angeles County-USC Medical Center.

The driver was described only as a black man in his 50s.

Anyone with information was asked to call LAPD Central Traffic Division detectives at 213-833-3713 or Detective Robert Palma at 213-486-0767 or the Central Traffic Division watch commander at 213-486-3713.
