An investigation is underway after a gunman opened fire on a family’s vehicle as they were traveling on the 110 Freeway in downtown Los Angeles Friday morning.

The incident began around 4:45 a.m. when a family in a Toyota Camry became involved in a “highway violence altercation” as they were traveling northbound on the 110 Freeway near Manchester Boulevard, the California Highway Patrol stated in a news release.

A few moments later, the driver of the Camry said he heard a gun shot that struck the left rear window of his car.

The driver exited the freeway and called 911 after stopping near the intersection of 6th and South Figueroa Streets, the CHP stated.

Video from the scene showed the family’s rear passenger-side window had been shattered.

The Camry was occupied by five people, including three children under the age of six, at the time of the shooting, according to the CHP.

No injuries were reported.

The suspect vehicle was described as a black Nissan Rogue believed to be occupied by a male driver and a female passenger.

The Rogue was last seen heading northbound on the 110 Freeway.

Anyone with information is asked to contact the CHP at 213-744-2331 or 323-259-3200.
