Children from more than 20 schools have taken part in a competition promoting online safety.
As part of Safer Internet Day, youngsters were challenged to create a two-minute video, a game or app around the theme of keeping themselves safe online.
Suggested ideas included cyber-bullying, sexting, the issues of social networking, privacy settings and online blackmail.
Chichester High threw open its doors to the area’s primary and secondary schools on February 7 where the winning entries were showcased.
West Dean School were named winners in Key Stage 2, with St Richard’s Primary coming second and Fishbourne third.
In Key Stage 3, first place went to Midhurst Rother School, with Chichester Free School second and Bourne Community College third.
In Key Stage 4, The Academy Selsey were the winners, followed by Chichester Free School and Chichester High School.
The winners received two laptops to take back to their school, courtesy of Ergo Computing, while those in second and third place won Amazon vouchers.
The judges were: PC Sarah Pack, of Chichester Police, Alan Mackenzie from www.esafety-adviser.com, Pam Bushby, communities intervention manager at Chichester District Council, Albert Seminerio from ERGO www.ergo.co.uk and Laura Marmolejo, public engagement officer for Chichester Police.
