18 year old Harry Vaughan had pleaded guilty to 14 terrorism offences and two of possessing indecent images of children.
The former Tiffin School pupil has been sentenced to two years' detention in a young offenders' institution, suspended for two years.
This is a correction from the former article " a former Kingston grammar school pupil who secretly promoted neo-Nazi terrorism online has been handed a suspended sentence."
Radio Jackie News would like to apologise to Kingston Grammar School for any confusion with the original article.
