In a statement, a GMP spokesperson said: “Emergency services were called to reports of a concern for welfare on Queensway in Swinton at around 10am this morning (Friday 19 June).

“A man – who was potentially suffering a medical episode – entered the school grounds with a brick, causing alarm to school staff and pupils and damaging a window.

“Officers arrived on scene quickly and gained control of the man, who was taken by ambulance staff to hospital.

“No harm was caused to any of the school staff or the pupils, and the school has made the decision to close for the day and send children home.”
