The bulletin issued by police in the southwest Ohio town of Springdale describes the subject as two feet tall, weighing eight pounds, clad only in blue pants and prone to sleeping in trees.
Dillion, a circus monkey, fled into a nearby woods early on Monday after being frightened by a train whistle from tracks near where the circus was performing in Springdale, in northern Hamilton County.
Trainer Philip Hendricks, who is part of the Hendricks Brothers Circus, says Dillion, who has a white face, brown body and is wearing a leash, is usually confident in new surroundings but the train whistle sent him scurrying.
The circus is leaving town Thursday morning and Hendricks is worried that his monkey won't be found before then.
Hendricks suggests that anyone who spots Dillion try to lure him with food. He's fond of apples, oranges, nuts, berries -- and Kentucky Fried Chicken.
