The Safer Living Foundation, which works to rehabilitate paedophiles, has been criticised for organising a Family Fun Day to raise funds and not making it clear to parents attending what their money was going to be used for.
Some parents have since stated that they would never have supported the event, held on Easter Saturday at the Keyworth United football ground in Nottinghamshire, had they had realised.
However the charity has said that its aims are prevention of paedophile offences as well as psychological help for those who have already offended and has apologised if some who supported them were not aware of this.
