Anti-knives campaigns took a creative route with children designing eye-catching posters to spread the message.

Primary pupils in London Colney schools were encouraged by police community support officer Debbie Daniels as part of the #livesnotknives campaign.

Selected posters have been on display at the Caledon Community Centre since the Larks in the Park event on June 30. They have since remained up to influence others around the area to prevent knife-crime.

St Bernadette’s Catholic Primary School, Hertfordshire, helped participate with the posters after Ahnsanullah Nawazai, aged 20, was murdered outside the school on November 28, 2018.

Ms Daniels said: “Whilst it is important for the police, parents and other agencies to educate children about important issues like carrying a knife, the message usually comes across much better if it is delivered by peer groups.

“The project was very positive and hopefully has made the young people think about their actions and will give them the confidence to question any friends who may be thinking of arming themselves with a knife.”

Other schools involved in the project include London Colney Primary School and Bowman's Green Primary School.
