Mr Wilkinson then said: “I’ll get someone to talk to you”.”He came out with the president, Mr Barnes. Harrison thought straight away that there was an attitude in the way that he came out. “Mr Barnes said: “Why would you not wear these colours? They’re perfectly good colours.”Mr Harrison said: “You get all sorts of colours here, I’m just not interested. You get blue and whites, referencing to other groups or gangs.”Barnes replied: “I hate black and whites, all black and whites should die.”And with that he flew in and headbutted him. Harrison said from then on the punches started to rain in.”They knocked his legs from behind so that he fell to the ground.”Mrs Penfold was told by Wilkinson: ‘If you talk to the police you and your children are next’.Barnes, of Washington, West Sussex, and Wilkinson, of Leonard’s-on Sea, East Sussex, both deny causing grievous bodily harm with intent.Later, Recorder Brian Altman QC discharged the jury and said the case was being put off until July.He said the reason was because the case was going to run over its two-week estimate, causing problems for at least two jurors.
