The cyber group posted a Web site displaying the personal contact information for Mayor Jean Quan and her husband, City Administrator Deanna Santana, police Chief Howard Jordan, City Attorney Barbara Parker and eight City Council members, the Oakland Tribune reported Tuesday.
"Anonymous has been watching. Since the inception of Occupy Oakland, We have been actively monitoring your behavior, and exposing the identities and sensitive information of officers of the Oakland Police Department; as they have continued to act in an unprofessional and violent manner," the Web site read.
The group withheld the information for at-large Council Member Rebecca Kaplan.
"Thank you for your support and being a true leader in the community," the group posted alongside her name and office phone number.
Anonymous denounced what they called violent tactics the city used against Occupy protesters, as well as budget cuts resulting in school closures and reductions in services.
"The people on this list are supposed to represent the best of what the city of Oakland has to offer. If they are the best, why is there so much trouble within the Police Department, and in the city of Oakland?" the Web site said. "We are shocked and disgusted by your behavior. Before you commit atrocities against innocent people again, think twice. You should have expected us."
