WESTMINSTER, Calif. (KABC) -- Two people were killed and three others were injured Saturday morning in a multi-vehicle crash on the 405 Freeway in Westminster, authorities said.
The California Highway Patrol issued a Sigalert after the 4 a.m. pileup and shut down all southbound lanes near Bolsa Avenue.
One of the five vehicles involved in the collision erupted in flames after its occupants escaped, a CHP spokesperson said.
Two individuals were pronounced dead at the scene and two others were rushed to UC Irvine Medical Center in unknown condition. A third survivor suffered minor injuries.
"Impairment" may have been a factor in the crash, which was allegedly triggered by a motorist in a speeding black Honda, CHP Officer Duane Graham said. That driver was one of the three people hospitalized.
CHP officials later confirmed an arrest was made. It's unclear what charges the suspect may be facing.
All lanes were reopened shortly before 10 a.m., according to a CHP incident log.
