Attend any Magistrates? Court ? Present your evidence ? including any witness statements and if possible, ask same to make an affidavit ? Solicitor will only charge ?5 for this [ if you present your affidavit / not asking them to type one up. They will take a copy for safekeeping ? look-up on the net how to formulate an affidavit ? Ask for a summons to be issued by the Court against ????? for a criminal offence????? QUOTE the precise offence ? Law and what subsection if any. Will be expensive if you fail to win your case. Court costs and the defence costs: If the police fail to prosecute ? asked for reason and if you disagree make a complaint. ps: You can swear an affidavit at any Court ? Mostly having to wait all day for cases to finish. Good Luck.
