Bristol's two Oasis academies are calling on other schools to join them in supporting the global campaign Stop The Traffik.

The aim is to make young people worldwide more aware of human trafficking, and the issues surrounding it.

A Start Freedom programme is being launched on Wednesday with a webcast from the United Nations building in New York, which will appear on the website at 9am.

Oasis Academy Brightstowe in Shirehampton and Oasis Academy Bristol in Hengrove are asking students in other academies, schools and youth organisations across the city to log on to www.startfreedom.org, where they will be able to watch the broadcast online, and sign up to become part of a united global voice seeking to stop human trafficking.

Nikky Mungeam, of Oasis Brightstowe, said: "We are proud to be spearheading this campaign. We've done a fair bit of work already to make our school community aware of the issue of human trafficking, including setting up a local campaign group. It would be great to see more local schools backing Stop The Traffik, as it's something our young people really feel passionate about."

Rebecca Clark, principal of Oasis Bristol, said: "All of our students are horrified at the actions of some people who want to sell human beings for their own profit. They want to join this campaign, which seeks to stop human trafficking."
