A company director who volunteered at a leading private school has been jailed after being caught with a sickening horde of child abuse material.
David Rankine, who built-up a leading media firm, was given an extended three year sentence when he appeared in the dock at Perth Sheriff Court.
Rankine, 42, was well-known as a first aider who was often called in to offer treatment to young pupils at £14,000-a-year Dundee High School.
