British Police Arrest Suspected LulzSec Hacker

British police arrested a 19-year-old man who may be linked to the online hacker group LulzSec, the latest development in a global law-enforcement scramble to contain an outbreak of cyber attacks aimed at companies, governments and other entities. The arrest came as the U.K.'s Office for National Statistics Tuesday said it is investigating whether computer hackers have stolen data from the 2011 Census.
