(CNN) -- An investigation into alleged misconduct by subordinates of Sheriff Joe Arpaio in Arizona's Maricopa County ended Wednesday with a report submitted to the self-proclaimed "America's toughest sheriff."
No details of the investigation by Pinal County Sheriff Paul Babeu were released. A statement by Babeu's office said he turned over to Arpaio the 1,022-page report and three additional "findings of fact" regarding Arpaio's chief deputy, David Hendershott, Director Larry Black and Capt. Joel Fox.
In a letter to Babeu, Arpaio noted that privacy limits prevent disclosure of findings from the investigation until any appeal process has been completed.
"As a result, we may be precluded from discussing or releasing all or portions of the investigation report until these employees have received the due process to which they are constitutionally entitled," Arpaio's letter said.
The investigation followed a memo written by another Arpaio subordinate alleging misconduct in the sheriff's office.
Arpaio also faces a Justice Department investigation into whether his policies cracking down on illegal immigrants discriminate against Hispanics.
