A juvenile has been arrested for allegedly stealing items from parked cars in Easton. Police received a call early yesterday morning from a Bayberry Lane resident about vehicles in his driveway being entered.  The resident followed the getaway car a short distance, while an Easton officer saw the suspect heading south on Route 59 at a high rate of speed.  The officer did not chase the vehicle onto the Merritt Parkway northbound as a safety precaution, but did come across it, crashed, a short time later.  One person was taken into custody.  Another suspect fled the scene on foot and was not apprehended.  The crashed car was reported stolen out of Waterbury last Wednesday.  The juvenile was charged with larceny and simple trespass and released to a parent.  Easton Police Chief Richard Doyle urged all residents to not leave their keys and valuables in their vehicles, and to make sure they lock their vehicles.
