Federal officials say a confidential source told them in Sept. 2011 that Osmakac wanted al-Qaida flags. Two months later, the federal complaint said, Osmakac and the confidential source "discussed and identified potential targets in Tampa" that Osmakac wanted to attack.

Osmakac allegedly asked the source for help getting the firearms and explosives for the attacks, and the source put him in touch with an undercover FBI employee.
