The email, seen by BBC News NI, prompted urgent responses from the Police Service of Northern Ireland (PSNI) and the Education Authority (EA). The PSNI said it had received reports of the email and was conducting urgent enquiries, liaising with schools. The EA acknowledged the concern and stated it was working closely with police, issuing communications to support school leaders.
Some schools reacted by evacuating. St Colman's PS Lambeg asked parents to "come immediately" to collect children, adding "please don't panic the children are all safe." Harpur's Hill PS and Rosstulla Special School also advised parents to collect pupils. Other schools chose to stay open while seeking police guidance.
The threat affected over 100 schools in the region. Authorities have not confirmed the credibility of the claim, but the PSNI said an update would be provided in due course. The Department of Education has been contacted for comment.
This incident follows a pattern of similar threats to institutions, and the investigation is ongoing.
