Georgia was also been awarded £20 of book tokens after her winning design was chosen over entries from all 4th and 5th year pupils at the school.

The screensaver will now be used on all computers at Ash Tree.

Shirley Morris, chairwoman of the GDCPP, said: "Bullying in any form is wrong and through this competition we are able to introduce that principle to young people.

"This message is then reinforced to all pupils at the school through Georgia's simple but effective design which will be seen on every computer used at the school."

PC Elliott added: "The GDCPP aims to initiate crime prevention projects to help the local community. This project was seen as an interesting and fun way for the children to learn about bullying and design."
