A tree was knocked down by a car outside the Sandy Hook Volunteer Fire & Rescue substation.  Newtown Police are looking for the driver that also damaged the lawn last week.  Police say the accident happened sometime between May 31st and June 3rd when the vehicle left the roadway.  The substation is located on the corner of Berkshire Road and Nighthawk Lane.  Anyone who may have seen or heard anything suspicious in the area during those dates is asked to call Officer Steven Borges at 203-426-5841.
