The Metropolitan Police say that a 19-year-old man they’ve arrested is “Topiary,” the spokesman for LulzSec (AP)

Scotland Yard said Wednesday that it has arrested a 19-year-old hacker linked to hacking group LulzSec.

According to a Metropolitan Police statement, the man is believed to be “Topiary,” who has been represented as a spokesman for the hacking group. The statement also said a 17-year-old man is being questioned in connection with the LulzSec attacks, but has not been arrested.

In a related development, LulzSec and Anonymous called for its supporters to boycott their PayPal accounts Wednesday in protest of reports that the online payment site assisted the FBI with raids on Anonymous. Threat Level reported that the FBI is working off a list of 1,000 IP addresses responsible for the most protest traffic when PayPal decided that it would close down an account supporting the whistleblower site Wikileaks.

“Quite simply, we, the people, are disgusted with these injustices,” the groups said in their release, addressing PayPal and the FBI. “We will not sit down and let ourselves be trampled upon by any corporation or government. We are not scared of you, and that is something for you to be scared of. We are not the terrorists here: you are.”
