Authorities say a California Highway Patrol motorcycle officer has been severely injured in a crash that has closed the northbound 405 Freeway in Los Angeles.
CHP spokesman Sgt. Mark Garrett says the two other vehicles were involved in the crash around 8:30 a.m. Wednesday near Interstate 10. It was not immediately clear if anyone else was injured or what caused the wreck.
The northbound freeway is closed between Venice Boulevard and I-10, causing major traffic on both sides.
