Authorities on Tuesday conducted a series of wide-ranging arrests of top members of LulzSec, a computer hacker group that has claimed responsibility for a string of high-profile cyber attacks on government agencies and large companies.
The arrests included one person in Chicago, two from Ireland and two from Britain, according to a law enforcement source with knowledge of the investigation.
Authorities had been investigating the suspects, helped in part by a leader within the organization who had been secretly working with government officials
Details of the case are expected to be released soon in an indictment in New York federal court.
