County Sheriff Jim Janecek said he met with Matthew and Rowena Schade and their children.
Matthew Schade was arrested on a warrant for a probation violation, authorities said in a news release. His wife was being held by order of the Nebraska Department of Probation, it said. It did not specify a reason.
The release did not address the condition of the two children, ages 8 and 11. State health officials plan to meet with them before a determination is made concerning their placement.
The children, ages 11 and 8, will be placed after state officials talk to them.
The family disappeared March 20 after they were interviewed in their Creighton home about allegations of abuse.
A search extended to remote areas of South Dakota before winding back to Nebraska last week.
