Hello! Thank you for using Just Answer. My name is***** have over 12 years of legal experience.
ANSWER: It sounds to me that, based on what you've described, an adult committed the California offense battery (the actual use of force or violence upon someone else), under California Penal Code 242.
I cannot really tell you what to do. Only you and your family can decide whether you want to pursue charges. Just because you and your son decided to let it go a few days ago, it does not mean you are forever precluded from pressing charges.
So you can still go to the police department and ask them to pursue charges. But be advised that just because you ask them to does not mean the police or DA will pursue it. They will investigate first and then make a decision.
