Narrative:

Prior to this first flight of the day, the first officer performed a thorough preflight of the outside of the aircraft. Nothing was found out of the ordinary during this preflight. After arriving at our destination company personnel discovered a pencil sized puncture in the side of the aircraft by the forward cargo door. We were contacted and notified of this damage later in the day by our company security departure, who is investigating this and two other similar incidents. Supplemental information from acn 634454: I was assigned to work aircraft for overnight maintenance. Aircraft damage was noted on aircraft right, fairing forward of aft cargo door. Damage was a puncture of 3/8 inch. To my knowledge, damage was not present at time of overnight check.
