Oakland's top officials -- including mayor Jean Quan -- became the latest targets of the hacking group "Anonymous" Tuesday morning.

According to ABC affiliate KGO-TV, "Anonymous" has released the personal information of of city officials, including Mayor Quan, the city council, the city administrator and the police chief.

City officials' home addresses, phone numbers, birthdays and email addresses are the information the hacktivist group has made public.

The group's decision to "d0x" Oakland's top officials stemmed from the treatment of "Occupy Oakland," they said.

"We have been actively monitoring your behavior," the group said in a message. "You tear gassed us and arrested us and beat us. 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 the city of Oakland?"

"D0xing" is a regularly used "Anonymous" tactic, which lead to the world knowing the identity of the pepper spray cop at the University of California-Davis.

Over 400 "Occupy Oakland" protesters were arrested last week during clashes with city police.
