Ferdaus’ lawyers are asking that the 26-year-old be released on bail and placed in the custody of his father while he awaits trial.

Prosecutors, however, argue that Ferdaus is dangerous and should be locked up until trial.

Ferdaus was arrested in September after law enforcement agents posing as al-Qaida members delivered what he believed was C-4 explosive.
