CHICAGO AP – Two men unconnected to each other or to the investigation that has spawned recent national terrorism warnings are in federal custody after attempting to detonate what they thought were bombs outside an Illinois courthouse and a Texas skyscraper, authorities said.

Michael C. Finton, 29, who also went by the name Talib Islam and idolized American born Taliban soldier John Walker Lindh, was arrested Wednesday in Springfield, Ill., after federal officials said he attempted to set off explosives in a van outside a federal courthouse in the Illinois capital.
