A pickup truck that slammed into a motorcyclist who was riding with a group on the 210 Freeway Saturday night may have done so on purpose.

The L.A. Times reports that around 7 p.m. last night, six motorcycles were heading west on the freeway in the number one lane, traveling about 65 mph just west of Irwindale Avenue in Irwindale. According to the CHP, a black pickup truck suddenly crossed all the way from the number four lane into the one lane, and hit one of the motorcyclists. A chain reaction was sparked with the five other motorcycles—two of them hit a BMW that was traveling in the carpool lane.

According to a statement from the CHP, "preliminary information indicates the pickup truck may have intentionally struck the motorcycles." The San Gabriel Valley Tribune notes that the drive of the pickup truck fled the scene, and no more detailed description was available.

City News Service writes that the six motorcyclists suffered major injuries and were transported to local hospitals. along with two passengers from the BMW, to local hospitals. According to KTLA, four people had been in the BMW, and two of those passengers were also transported to a hospital. No word yet on their conditions.
