ANSWER
I said that Vermeulen is someone who speaks mainly Northern Sotho and he spoke in Northern Sotho that we should assault this person because he is not telling the truth and he was saying that while assaulting this person, after asking him a question because as I said Joe was also disputing what he was saying because Joe also knew him and knew the area where he was staying.   I was also told to assault him and that's when I assaulted him, severely.
