Yesterday, 'mass hysteria' closed a school in Barnsley. According to an article in The Times, 30 or so pupils began feeling ill after watching a widely used biology video, and as other pupils heard about the malady, the effect spread.

The school officials eventually gathered everyone together in the school hall suspecting a gas leak, and paramedics advised the school should be closed.

The original class were taken to hospital, but no signs of physical illness have been reported and no gas leak has been found. The episode has been put down to 'mass hysteria'.
