The Antioch Police Department is searching for people involved in a vehicle-to-vehicle shooting that occurred Tuesday morning, according to a news release.

The shooting occurred near the Dutch Pride Gas and Food on the 500 block of East 18th Street around 11:24 a.m., authorities said.

Police received multiple calls reporting the sound of gunshots and a vehicle collision. The callers reported seeing a man armed with a gun fleeing a silver sedan that was left disabled in a parking lot, authorities said.

When officers arrived on scene, they found the silver sedan in the parking lot of 511 East 18th Street, authorities said.

In their initial investigation, officers learned that the driver of the silver sedan had been traveling eastbound on East 18th Street away from the gas station when a person in a dark-colored sedan traveling westbound opened fire as they passed the silver sedan, police said.

The silver sedan then swerved and hit cars in the parking lot, authorities said. A man, carrying a gun, and a woman left the silver sedan and ran in different directions. The man ran northwest and jumped fences, witnesses told police.

The dark-color sedan fled the scene at high speed and was not located by police. Police did not locate either occupant of the silver sedan, authorities said.

Rocketship Delta Prep School, which was located near the incident, was placed on lockdown out of “an abundance of caution” until the scene was declared safe, police said.

The investigation into the incident is still in its preliminary stages, authorities added.

Police asked anyone with information about the incident to contact the Antioch Police Department non-emergency line at (925) 778-2441 or the investigations bureau at (925) 779-6925.
