The Jacksonville Sheriff's Office was called to a home in Woodland Acres about 2 a.m. Monday after a domestic dispute between two brothers.
The home was located in the 6900 block of Oakwood Drive, south of the Arlington Expressway.
A JSO investigator on scene told Channel 4 an "item of concern" was found, but the items were not bomb-making materials.
One of the men involved in the dispute was taken into custody. His name and other details were not released at the scene.
