So-called 'Simple Assault' in most(all?) jurisdictions is a "probable cause misdemeanor" and, unlike the vast majority of other misdemeanor offenses (which must be committed in the officers presence for an arrest to be made), you can be arrested for it based on probable cause alone.

Many different national laws allow for what is formally known as "citizen's arrest". You can arrest someone and turn them over to the police, if circumstances warrant. Of course, if circumstances do not warrant and you decide to arrest someone anyway, you can be charged with false imprisonment or kidnapping. So do not abuse this law. Acceptable circumstances vary from country to country, and can include; - Directly witnessed the crime being committed, - Preventing the criminal from escaping before police can arrive, - Preventing the renewal or continuation of criminal damage, - Preventing the injury of either the public, or the criminal themself, - Some countries allow any citizen to arrest someone who has escaped from prison or custody.
