Federal prosecutors are opposing bail for a Florida woman accused of making threats that caused a lockdown of the nation's sixth-largest school district.

Prosecutors said at a hearing Tuesday that 48-year-old Ellisa Martinez of New Port Richey on the Gulf Coast is a danger to the community and is likely to flee before trial. A judge set a Monday bail hearing. Neither Martinez nor her court-appointed attorney would comment.

Martinez was flown to South Florida from Los Angeles, where she was arrested last month.

Prosecutors say Martinez sent a threatening e-mail Nov. 10 to a conservative radio host mentioning a potential shooting at a school or government building. That caused lockdown at nearly 300 Broward County schools, affecting about 275,000 students.
