Alexander Stefan Dombovic is out of custody on $50,000 bail.
The assault occurred when a 13-year-old Portola Valley boy heard a car in the driveway of his home, and saw a man rummaging through his father's vehicle. The boy asked the man what he was doing, and the man allegedly struck the boy on the shoulder with a bat.
The man fled in an SUV, and deputies, in the area on another matter, saw the SUV with lights off heading directly at them on the wrong side of the road. They swerved to avoid a collision and began a car chase. In the 900 block of Westridge Drive, the SUV plunged down an embankment. Deputies said they found about 129 pieces of mail from 18 local addresses in the car.
