Cars were being detoured around the closure but being allowed to re-enter the freeway past the area of the police activity.  An ambulance was seen leaving the area at about 6:53 p.m.

There appeared to be two vehicles being inspected by authorities at the side of the freeway. So far, there has been no confirmation of what type of incident authorities are investigating.

Authorities later confirmed that the activity was centered around a shooting investigation.

CHP later confirmed that a driver, described as a black male in his 30s or 40s, was driving a dark colored sedan when he began shooting at the right front passenger door of a green Toyota RAV 4 occupied by two males.

The driver of the Toyota was wounded by gun fire. Both the driver and the passenger were transported to an area hospital where the driver is being treated for his injuries. The driver’s injuries did not appear to be life threatening.

A bullet hole could be seen on the passenger front door of the Toyota.

Authorities reopened the freeway shortly after 8:30 p.m.

The closure created a large traffic back-up as vehicles are forced to exit the freeway in a single lane prior to re-entering.

The freeway shooting is one of several in the East Bay this year alone.

In March, CHP investigated three targeted freeway shootings in three days. Most of them occurred during broad daylight.
