The woman who was charged with threatening children at Bishop Feild Elementary on Monday is a long-term offender.
Nancy Harte, 49, is charged with mischief and uttering threats to cause bodily harm to children.
The RNC said the threats were made over the phone. Harte allegedly called police, threatened to hurt children, and named Bond Street, where the school is located.
That prompted police to take the threat seriously, and the school was secured.
Parents were asked to pick their children up at Bishop Feild around 11:30 a.m. Monday.
There's no word on the type of threat that was issued.
On Tuesday, Harte was sent for a psychiatric assessment, and was deemed fit to stand trial.
She is currently in custody, and has waived her right to a bail hearing.
Harte is due back in court on June 25.
Harte has a lengthy criminal record, with charges that date back to 1989. Those charges include sexually assaulting an infant, arson, assaulting a peace officer, and threatening animals. She has also previously spent time in prison.
In 2001, she was named the province's first female long-term offender.
Harte is still under a 10-year supervision, which is the maximum that a person can receive under the criminal code.
