Around 11 a.m. police said that students and staff were being allowed to return to the school.

This is the second bomb threat the school has experienced over the course of a week.Glendale Public Secondary School was one of two facilities that were targeted by bomb threats on March 21.

Officers cleared the school about an hour after the threat was made in that instance, allowing staff and students to return.
