Marcos, Hydar said. "Deputies tried to pull the stolen car over, but the driver did not stop, resulting in a vehicle pursuit through the cities of Vista, Carlsbad and Encinitas," Hydar said. "Sheriff's ASTREA Helicopter assisted in locating and following the stolen car from the air, enabling the patrol units to stop pursuing." The helicopter provided updates on the stolen car's location as the ground units followed, the sergeant said. The driver exited southbound Interstate 5 at Encinitas Boulevard and collided with an MTS bus, Hyder said. No one on the bus was injured. The driver then fled the stolen car and was apprehended by deputies, authorities said.
