A 71-year-old man died Tuesday afternoon after trying to stop a tractor-trailer from rolling away in Rochester Township.

Beaver Valley Regional police Chief Michael Priolo told TribLive news partner WTAE contractors were unloading a trailer at the Sherwin-Williams plant on Cleveland Street when their truck began to move.

The man was hit and pulled underneath the tires and he and other contractors attempted to stop the vehicle. He was pronounced dead at the scene.

Authorities have not released the man’s name.

Police said the truck was not in park at the time of the accident.

Pennsylvania State Police are investigating.
