An unstable chemical has been made safe by an Army bomb disposal team in Co Tipperary.
The Picric Acid was found in a laboratory at CBS in Thurles.
The school was evacuated and a nearby road was closed off to traffic during the incident at around 7pm.
The scene was declared safe at 8.30pm after a controlled explosion was carried out on the acid at a safe location.
Picric Acid is more commonly known by its chemical name "trinitrophenol", which is a re-agent routinely used in laboratories around the country that can become unstable over time.
