A woman who was arrested Monday after officials dismissed students from Bishop Feild School in downtown St. John's over an unspecified threat is now facing a pair of charges.

The woman, 49, was later charged with uttering threats and mischief. 

RNC Const. Steve Curnew said she is due to appear in court Tuesday morning.

He would not comment on whether or not the woman had a connection with the school.

Parents were called to Bishop Feild School on Bond Street to pick up their children by 11:30 a.m. As they arrived, RNC officers assured them their children were safe. 

Tony Stack, the assistant director of education with the Eastern School District, said a community breakfast was underway at the school when the threat was called in.

"Our focus was getting them into a secure mode. They were in their classrooms," Stack told reporters.

"There was RNC presence here throughout — later on, a more robust presence, at which time the dismissal took place."

Social media faster than school alerts

While the school issued alerts to parents, some who arrived on Bond Street said they learned about the situation from posts on social media, including Facebook.

"There would have been a number of parents [who] were in the building when the threat was advised by the RNC," Stack said.  

During the morning, parents were only allowed into the building one at a time, so that each parent could be matched with his or her children.
