Answer: A person can arrest any other person committing what they call an arrestable offence. But only a police officer can arrest someone on reasonable suspicion of an arrestable offence. If he doesn't see it, but thinks someone did it, then they can arrest them. If you see a police officer do something illegal, you can arrest them. But you'd be taking your life into your own hands as the chances are, the policeman would have a professional explanation for what happened
