A driver wounded in a car-to-car shooting on the 91 Freeway called 911 and followed the alleged gunman until officers arrived and took the other driver into custody, officials said.
The shooting took place about 4:15 p.m. Monday at the 91 and 5 freeway interchange, the Anaheim Police Department said. Both vehicles continued on the eastbound 91 Freeway before stopping near the Weir Canyon Road exit in Anaheim Hills.
The California Highway Patrol said the victim stayed on the phone with dispatchers for about 10 miles as he pursued the other vehicle until officers came to help.
The victim, a man in his 50s, was taken to the hospital with non-life-threatening wounds. He told NBC4 he was shot three times in the arm.
The victim said he didn't know why he was targeted, but was the "total victim" in the shooting.
Aerial footage showed bullet holes on the driver side of the victim's white Ford Expedition, which was parked on the shoulder of the freeway. The other vehicle was also stopped on the shoulder several yards away.
The other driver was taken into custody and questioned in the shooting, Fullerton police said. He had what appeared to be a paper bag wrapped around his hand as he was led away by officers to the back of a squad car.
All lanes of the eastbound 91 Freeway in Fullerton were shut down as investigators searched for evidence.
Friends of the victim told NBC4 he used to be a police officer, but the victim did not confirm or deny any affiliation with law enforcement.
Officials said there was an exchange of gunfire, but later reported that it was unclear whether the other driver also fired a weapon.
The incident comes less than three weeks after a father of four was gunned down on the westbound lanes of the 91 Freeway in Anaheim.
