Initially it was thought that the complaint had originated from a parent of one of the children at the school. However, it was later revealed that an office assistant employed at the school, Sara Khawad, had filed the complaint and was the key witness for the prosecution.[5] Khawad was said to be angry with the school's head teacher. "I was used by the secretary to get at the school", Gibbons told The Guardian shortly after her release.[2]
