A 19-year-old East Haven woman faces a federal charge that she threatened to carry out a violent attack at Gateway Community College.

U-S Attorney for Connecticut David Fein says the complaint alleges that Amanda Bowden  sent text messages and later spoke with an undercover agent,  making a detailed series of threats claiming she planned a mass murder at the New Haven School.  In the communications the first two weeks of this month,  she claimed to possess firearms and to have built at least two napalm-based bombs at her home.

She was arrested on state charges Tuesday,  No firearms or explosive materials were found in a search of her home.

If convicted on one count involving false information and hoaxes,  she could be sentenced to up to five years in prison and fined up to a quarter million dollars.
