An antique cannon has been stolen from the replica of an early 1800's military fort in downtown Fort Wayne. A volunteer at the Historic Old Fort found the cannon was gone on Tuesday and reported the theft to police. Volunteer Norman Gable tells The Journal Gazette that group members who fire blank loads in the cannon undergo extensive training and it could be dangerous for whoever stole the cannon to shoot it off. Volunteers say the cannon weighs about 200 pounds and is made of pig iron, so its scrap value is minimal. Old Fort volunteer Sean O'Brien tells WANE-TV the group wants the cannon returned and a reward will probably be offered.
