I caught this on the Fox News website:

As a result of Monsegur’s cooperation, which was confirmed by numerous senior-level officials, the remaining top-ranking members of LulzSec were arrested or hit with additional charges Tuesday morning. The five charged in the LulzSec conspiracy indictment expected to be unsealed were identified by sources as: Ryan Ackroyd, aka “Kayla” and Jake Davis, aka “Topiary,” both of London; Darren Martyn, aka “pwnsauce” and Donncha O’Cearrbhail, aka “palladium,” both of Ireland; and Jeremy Hammond aka “Anarchaos,” of Chicago.
We met Darren at CampusCon - He gave a talk at the event. Don't know that Donncha lad. Will send Darren a tweet and see what the craic is.
