IRWINDALE, Calif. (KABC) -- At least four people were critically injured when authorities say a pickup truck intentionally struck a group of motorcyclists on the westbound 210 Freeway in Irwindale Saturday night.
The collision occurred west of Irwindale Avenue around 7 p.m., according to the California Highway Patrol.
Investigators say six motorcycles were traveling in the No. 1 lane on the westbound 210 Freeway at approximately 65 mph when a black pickup truck traveled from the No. 4 lane, across the westbound lanes, into the No. 1 lane and struck one motorcycle.
The incident caused a chain-reaction crash involving at least five other motorcycles. Two of the motorcycles involved then struck a BMW, which was traveling in the HOV lane.
CHP officials say the pickup truck may have intentionally struck the motorcycles. No further details on what led up to the crash were released. A description of the driver of the pickup truck was not immediately available.
Four patients were transported to a local hospital in critical condition. Three others suffered minor injuries and an eighth person refused medical attention, CHP officials said.
The crash prompted a SigAlert, which closed several westbound lanes for at least two hours.
The investigation is ongoing. Anyone with information is asked to call the California Highway Patrol's Baldwin Park Station at (626) 338-1164.
