Authorities are investigating after a man was fatally struck by a vehicle in an apparent hit-and-run in Riverside Monday morning. 

Around 1:45 a.m., California Highway Patrol officers responded to a report of a crash involving a vehicle and a pedestrian on the southbound 215 Freeway, according to a CHP news release. 

Police say the driver of either a Honda SUV or pickup was traveling southbound on the freeway and drifted onto the right shoulder where it crashed into a man who was putting gas in his disabled truck.

The driver of the vehicle then fled the scene on the southbound side of the freeway.

The victim, a 38-year-old man from Lake Elsinore, was fatally injured and died at the scene.

The Honda sustained damage to its right side and detectives said they have recovered some broken parts.

This investigation remains active and anyone who has information or may have witnessed the the crash is urged to contact CHP at 951-637-8000.
