CENTRAL ISLIP - A Lake Ronkonkoma woman accused of making phony bomb threats to an Arizona airport was arraigned in court today.

Federal authorities say 37-year-old Mary Purcell wanted to keep her mother and brother from flying to New York on a date near the Sept. 11 anniversary so she called the airport and falsely claimed a bomb was on board their flight.The FBI says Purcell called Tucson airport police twice to say she had overheard details of a bomb plot targeting a Southwest Airlines flight on Sept. 10.

The threat led authorities at the airport to remove luggage from Flight 2475 and conduct a search. No bomb was found.

Purcell was released on a $200,000 bond that was co-signed by her mother and brother. Prosecutors say she was already on parole for a forgery conviction when she was arrested for allegedly making the false bomb threats.

Purcell faces up to 10 years in prison, if convicted.
