NORRISTOWN, Pa. (Reuters) — An elementary school teacher's aide confessed to making a series of bomb threats at local public schools since March 2 to get back at unfriendly co-workers, authorities said Friday.

Denitra Patrice Fisher, 21, who worked with autistic children at Whitehall Elementary School near Philadelphia, allegedly used pay phones to make six bomb threats to public schools, including her own.

The threats, the last of which occurred Thursday, forced the evacuation of thousands of students from four schools in the Norristown Area School District. School officials complained of lost class time and unnecessary stress.
