A team assigned to review more than 6,500 child abuse and neglect reports that weren't investigated by Arizona child welfare officials says they have now assigned more than 3,100 of those cases to investigators.

The team named nearly three weeks ago by Gov. Jan Brewer provided the latest update Tuesday.

It said more than 1,500 children identified in the reports now have been seen and more than 1,300 cases have had a response.

The team is led by the head of the state's Juvenile Corrections Department, Charles Flanagan.

Department of Economic Security Director Clarence Carter on Nov. 21 revealed the uninvestigated reports called into a hotline.

He has placed five senior Child Protective Services workers on administrative leave while an investigation is underway on how the cases were illegally closed.
