The father of a missing Arizona girl is forbidden to see his two other children.

FOX News Radio's Lisa Lacerra reports:

Authorities in Tucson say the father of Isabel Celis, the six-year-old missing for nearly a month, was alone with her when she vanished, but it doesn't make Sergio Celis a suspect and they say the couple's two boys are staying with their mother.

(Villasenor) "A voluntary agreement was reached between Child Protective Services and the parents to restrict access or voluntarily for Sergio to get some space and distance away from the two older children."

Tucson Police Chief Roberto Villasenor. Police say the girl's mother went to work the morning of April 21st and Sergio Celis later reported the little girl missing.
