Secret witness

When someone has important information about something bad that happened, they may be scared or worried to tell the police. So, they can choose to be a secret witness. This means they tell the police what they know, but they don't have to give their name or show their face. It's like playing a game of hide-and-seek where the witness gets to be the one hiding. This can help keep the witness safe and protect them from any bad guys who might want to hurt them. The police will still use the information the secret witness gives them to try and catch the bad guys and make things better.
