Fresno County's HEAT Team, which stands for Help Eliminate Auto Theft ... made a bust at "Extreme Connections" ... a car stereo shop in Central Fresno.
Officers say they found three stolen vehicles, methamphetamine, and some cash. Authorities searched two other locations, where they discovered another stolen vehicle.
They say this was a very sophisticated operation.
CHP Officer Leonard Sherman said, "Showing a level of sophistication, we have titles, paperwork, federal stickers, and labels, all of the things that go along side the counterfeit side of vehicle theft."
Authorities say they discovered higher-end vehicles like Escalades and Yukon's. They're still questioning several other people.
