Newtown Police are searching for a driver who allegedly used a machete to damage another vehicle in a road rage incident this week.  Police responded to South Main Street near Mile Hill Road Monday afternoon and were told that a driver got out of a tan car, with Florida plates, and damaged the other driver's car with a machete.  The man was described as having tan skin, being about 5-foot-10 to 6 feet tall with short brown hair.  Anyone with any information is asked to contact Newtown Police.
