The incident is believed to have happened in the school canteen at Holy Cross College, Strabane at lunchtime.
Alliance Party member, Stephen Connolly, from Omagh posted a message on Facebook saying: “Details remain unclear but I hope the situation in Strabane’s Holy Cross College is under control and that staff and pupils are safe. Concerned to hear that pupils and staff have been injured.”
A spokesperson for the PSNI said: “All parents of the pupils involved have been contacted. No serious injuries have been reported at this stage.”
