“An off-duty deputy was traveling west on the 118 Freeway when a person in the car in front of him rolled down the window and fired off several rounds into the brush alongside the freeway,” Saucedo said. The deputy, who was in a department cruiser, pulled the car over and found two men and two women in the car.

The male passenger was arrested for firing the gun and one of the women was taken into custody on an outstanding warrant, he said. The car was impounded and the other two people were released.

No gun was recovered in the car, Saucedo said.

“The people in the car admitted they tossed the gun out of the car when they realized a black and white was behind them,” Saucedo said.

The sheriff’s department asked the California Highway Patrol to shut down the transition between the 118 and 405 freeways at about 10 p.m. Tuesday and to stop westbound traffic on the 118 Freeway to search for the weapon, Saucedo.

There was no immediate report on whether the gun was found.

The transition road was reopened by about 11:30 p.m.
