Thursday 3:49 p.m.
Surveillance video released shows two figures approaching the Bentonville square monument and one stealing a cannonball from the feet of the statue.
The Bentonville Police Department released the video.
As of Wednesday, Sheriff Shawn Holloway said he had no information on the theft.
The stolen cannonball was itself a replacement for one stolen several years ago, according to information from county officials. The stolen cannonball is smaller and lighter than the remaining three and was not secured to the monument.
"It's about one-third the size of the others," John Sudduth, the county's general services administrator said. Sudduth is in charge of building maintenance for the county. He checked the remaining cannonballs after learning of the theft.
"On the others there's a threaded rod in the cannonball and a threaded insert in the monument itself," Sudduth said. "So they are attached directly to the monument. This other one apparently was not attached in the same way."
