U.S. Arrests Alleged Computer Hackers

By CHAD BRAY

U.S. authorities are expected to announce criminal charges later Tuesday against six individuals associated with the online activist collectives Anonymous and Lulz Security, according to a person in law enforcement.

Those charged include individuals in the U.S. and overseas and several people have been taken into custody, according to this person.

FoxNews.com reported Tuesday that three members of LulzSec, a splinter group from the hacking collective Anonymous, had been arrested and charges had been brought against two others.

The charges are the latest development in a global crackdown on high-profile computer attacks for which some followers of Anonymous and LulzSec have taken credit in the past year.

Those attacks include denial-of-service attacks and computer breaches against corporations, banks and government affiliates.
