A man was injured Friday afternoon after a piece of equipment he was using toppled over on top of him.
The incident happened around 2 p.m. on the 2300 block of Army Navy Drive, behind a row of homes in the Arlington Ridge neighborhood.
The worker was using a stump grinder on an embankment when due to gravity the equipment tipped over, crushing the man’s legs and reported burning his face or upper body.
The man was transported via ambulance to the trauma center at George Washington University with leg injuries, including a broken leg, and burns. Police remained on scene to investigate and talk with a supervisor from the company for which the man was working.
