PHOENIX (AP) -- An Arizona ethics panel has disbarred Maricopa County's former top prosecutor for failed corruption investigations he and America's self-proclaimed toughest sheriff conducted, targeting officials who crossed them.
The panel concluded former County Attorney Andrew Thomas broke professional rules of conduct for lawyers in bringing unfounded criminal charges against two county officials and a judge in December 2009.
Lawyers pressing the case against Thomas say he and Arpaio investigated officials they were in political and legal disputes with.
Thomas and Arpaio have said they were working to fight corruption.
Arpaio does not face any punishments in the disciplinary case, but investigations by his anti-public corruption squad took center stage at hearings in the case.
