About a week ago I witnessed a man I had never met slap his child round the face. I reported this to 101 as I was concerned for the child. I have just had a phone call from the child's mother threatening to sue me claiming there is cctv showing I am lying and they are going to sue me and get me sacked from my job. I had never met either of them so had no reason to lie and despite them saying there is cctv I am still sure I saw what I reported. Is it possible for them to sue me. Really hoping someone can give me some info
