Politically-minded youngsters have high hopes that their unusual fundraiser can help put a stop to human trafficking.
The group from South Hill Church organised a vertical dash up the 21 flights of the KD tower on Saturday.
They raised £1,000 for two anti-slavery charities through the event, which had 65 competitors aged between 10 and 80. They also collected around 200 signatures.
Rebekah Keene, 16, said: “When I first heard about people trafficking I was shocked at how people could do this to other human beings. I want to be part of stopping this crime.”
Police and crime commissioner David Lloyd hopes to help tackle the problem by ensuring escort service ads are not a front for slave crime.
