With major sporting events known to increase human trafficking in the host city, Stop the Traffik has teamed up with the United Nations to install walk-in pieces of art - gift boxes - outside well known and busy London landmarks.

Baptist minister the Revd Steve Chalke is a founder of Stop The Traffik and a UN special advisor on human trafficking.

He said, 'Whether the 2012 Olympics will see an increase in the number of people trafficked to London we cannot know at this stage.

'What we want to focus on is the opportunity to engage the world with finding a solution.'
On the outside, these boxes have the look and feel of intriguing gifts, symbolising the enticing promises made by traffickers. 

However, on the inside they will contain a three dimensional, thought-provoking and interactive experience that will introduce all those who enter to the reality of human trafficking. It will also suggest ways in which visitors can help to bring an end to this global crime. 

The boxes play on the fact that human trafficking is an act of deception.
