U.S. Customs and Border Patrol (CBP) officers are searching for a fourth suspect in a pursuit following a "smuggling event" at a highway checkpoint Thursday.
Investigators told NBC 7 that the car reached speeds up to 100 mph during the chase.
CBP officers said a pursuit with a silver Ford Expedition started near the Pine Valley Border Patrol checkpoint on Interstate 8 around 5:11 p.m.
The vehicle stopped on the shoulder of Lake Jennings Park Road near Blossom Park Road in El Cajon at approximately 5:35 p.m.
Once they came to a stop, the vehicle began to billow smoke and the driver got out and ran away.
Shortly after, CBP officers detained the suspect, and he was taken to a nearby hospital. He was evaluated for non-life threatening injuries.
About 10 minutes later, two additional people suspected of being in the country illegally were also detained.
As of 6:00 p.m., officers were searching for a fourth suspect.
No other information was immediately available.
