The Ohio County Sheriff's Office and the Kentucky State Fire Marshal's Office are investigating 11 suspected arson fires in Ohio County since the end of last year.
The sheriff's office says six of the fires were set in December in the southern part of Ohio County. Recently, authorities have been seeing more fires in central Ohio County.
Late last week, a fire was set to a house on Sunny Dale Road and a large farm storage building on 69 North. Officials are looking into several leads, but need more tips from the public.
