Public Safety spokesman Bart Graves said officials do not believe the department's e-mail system was compromised, The (Phoenix) Arizona Republic reported.
For its part, the hacking group claimed to have accessed both personal and department information, the newspaper said.
"This leak has names, addresses, phone numbers, passwords, social security numbers, online dating account info, voice mails, chat logs and seductive girlfriend pictures belonging to a dozen Arizona police officers," the group claimed on its Web site. "We found more internal police reports, cops forwarding racist chain e-mails, K9 drug unit cops who use percocets and a convicted sex offender who was part of (Fraternal Order of Police) Maricopa Lodge 5."
The Republic said it was the second hack of the department in less than a week.
