"Topiary," a 19-year-old who allegedly serves as the groups' spokesperson, was arrested in his home and transported to a London police station, reports CNET. Cops also are searching the home of a 17-year-old in Lincolnshire. Gawker has more details on Topiary, calling him a "skilled and reckless showman" who co-founded LulzSec and helped fund it. His last tweet: "You can't arrest an idea." The move is part of an international investigation into hacking that saw arrests last week in the US, London, and Netherlands. Many were allegedly involved in denial-of-service attacks on PayPal and others last year.
