“However I would like to appeal for any potential witnesses to this incident of assault that took place on 11 June in Oxford.“Specifically, I would ask that anyone who believes that they were in or near Ship Street or Cornmarket Street on this night, please think about whether you may have seen anything that could relate to this incident.
