A school remains closed today after 20 people were exposed to a noxious substance.
Dyfed-Powys Police and Welsh Ambulance Service were called and 20 people were treated after reporting breathing difficulties and nausea.
It is not believed to be a dangerous substance and a 17-year old boy was arrested and an investigation is ongoing.
