The situation is difficult and you may by mistake make things more complicated. Firstly, try to avoid any kind of litigation. Secondly, keep in mind that whatever she has taken belonged rightfully to her; therefore, you have no right to make any police complaint; thirdly, you need to understand that your wife has responsibility towards you but not towards your relatives; therefore, you may need to change your mind-set as per your family needs.

Opinion : You may need to stay cool for the time being and let some more time pass through; meantime, you should consider reproachment with your wife and her parents. try visiting them with a stable and compromising mind without ego hassles.

It may better to consider living a good family life back with her, instead of considering divorce which is not a good viable option.

you must try and understand her point of view as well. as a man you are duty bound to maintain your wife and parents as well. there might be certain difficulties she faced while staying with your parents. you cannot completely ignore the fact that even parents in law fail to treat their daughter in law as their own daughter. you need to think of a way out. either go for tenanted premises with your wife or build a separate floor in the same property. in case you want to choose between parents and wife, file a divorce petition.

You must have a clear record that they have taken away all items. You can prefer a police complaint for criminal intimidation immediately detailing all the facts.
