You see here they were tracking the thieves driving recklessly through neighborhoods.
This is what it looked like after a helicopter patrol tracked a car that sped away from police.
"They're on Hoehn and Frontage Road. They're passing on the shoulder," a deputy said from the helicopter.
The driver hit a guardrail while trying to get onto southbound Highway 101 from westbound Highway 12.
As the car stopped on the side of the Baker Avenue off-ramp, you can see someone throw something out.
Deputies recovered the item, which was a cellphone.
They also say they found a large amount of suspected stolen mail in the car.
Deputies arrested four people.
