The suspect drove his black Chevrolet Silverado with license V305LU into pedestrians and cars waiting their turn to cross into the United States, Mexican law enforcement officers told NBC 7.
Emergency personnel rushed to the northbound lanes just south of the port of entry when the incident occurred around 2 p.m. on Monday.
Prior to that, the driver was involved in an altercation with a pedestrian, police said.
Mario Martinez, Tijuana's police director, said the suspect allegedly threatened a person with a razor on Avenida Manuel Márquez de León in the Zona Ríos.
When police approached the driver, he allegedly fled in his Chevrolet Silverado pick-up truck toward the border crossing.
As he fled, the driver hit five pedestrians, including an officer; rammed 17 cars and hit 12 mobile street vendors, police said.
Fresno resident Lori Ray and her boyfriend were in the area after a weekend in Rosarito.
"I just heard a lot of banging and crashing and then the sirens," Ray told NBC 7. She said their car was hit and pushed off to the side.
She said what happened next was terrifying.
"Locals, mostly vendors, people that were out on the streets, they had sticks and bats and all kinds of things, just waving them," she said. "They just beat the car, grabbed the people out of the car on to the ground."
She said the people with sticks and bats were beating the people who were inside the suspect's vehicle.
Municipal police arrested the driver and he was turned over to federal investigators.
U.S. Customs and Border Protection told NBC 7 the incident did not impact wait times at the border.
No other information was available.
