A child was injured in a rollover crash on Interstate 5 Sunday night and the driver fled the scene of the accident, California Highway Patrol officials confirmed.
The collision happened at southbound I-5 near Rosecrans Street and Old Town San Diego.
According to witnesses at the scene, a truck traveling on the freeway flipped over onto an embankment and landed along Jefferson Street. Upon impact, a child passenger was partially ejected from the vehicle.
Witnesses told NBC 7 they could see the child hanging out of the window following the crash.
Witnesses described hearing a loud boom during the collision. Some people at a nearby hotel and liquor store told NBC 7 they ran out to see what happened and saw the overturned truck in the roadway.
Witnesses say they saw a man get out of the truck and take off running south on Jefferson Street.
According to CHP officials, the driver did take off running immediately following the crash, but then returned to the scene to unbuckle the child from the vehicle. The driver then got scared and took off running, according to CHP.
That's when a good samaritan ran to the truck to help rescue the child. The child was taken to a local hospital. Officials say the injured child is between three and five years old.
CHP officials are investigating the crash and trying to figure out why the driver ran away from the scene. Officials are looking into whether alcohol or drugs were a factor in the collision.
