The principal of a secondary school in Northern Ireland has been warned by police to stay away from work after she received a death threat.

The Stormont Education Minister has condemned the death threat saying it was absolutely unacceptable.

Principal of Crumlin Integrated College Dr Annabel Scott, went back to her post last June having been suspended for two years following a highly critical inspector’s report on the school.

A number of people protested outside the college against her re-instatement.

Just before the start of the new school year, Dr Scott received a threatening email, and was advised by the PSNI to stay away from work.

Education Minister John O'Dowd said the death threat had caused great distress to Dr Scott and the wider school community.

He said police had begun an investigation, and were working with college authorities to ensure steps are taken to minimise the risk to any individual.

The board of governors at Crumlin Integrated College sent a letter to all parents to inform them of the steps being taken to protect the safety and well-being of pupils and staff following the receipt of the threat.
