drugs after a sharp eyed teacher spotted him carrying a white paper containing a plant-like material.

But principal Earnest Payette denied the school had a drug problem, calling the incident a "one-off''.

The 17-year-old student was arrested at the school on Thursday afternoon but so far no charges have been brought until tests have been completed.

Mr. Payette said: "The matter is under investigation right now. We're waiting for a Police report.''
