The U.S. National Highway Traffic Safety Administration, or NHTSA, will investigate a fatal Dec. 29 Tesla Inc. crash in Los Angeles, CNBC reported, citing the auto regulator.

The Los Angeles Police Department confirmed to CNBC that a 2016 Model S Tesla ran a red light in Los Angeles and collided with a Honda Civic, resulting in the death of the two occupants of that car. The two people inside the Tesla were injured.

According to CNBC, it could not be immediately determined whether Tesla's advanced Autopilot driver assistance system was a factor in the crash.
