A teenager has been arrested following an alleged pepper spray incident at a school.

Emergency services were called to Claremont High School, Claremont Avenue yesterday morning at 9.30pm to reports of a chemical spillage.

All staff and pupils at the school were evacuated as crews from London Fire Brigade cleared the building.

The London Ambulance service sent two ambulances and its hazardous response team to the scene and checked over eight people. No one was taken to hospital.

Firefighters found no trace of a chemical spillage but thought there had been a discharge of a pepper spray-like substance.

A 16-year-old boy, who is a pupil at the school, was arrested on suspicion of using pepper spray under the Firearms Act after a can was recovered from a bin.

He was bailed to return to a police station in January next year.
