Can you enter a rented apartment?

[Jared Christensen]

I have a tenant who I am trying to work with to get some back rent before I boot them out, I have a feeling they are moving and going to screw me anyways but in one of their pictures on Facebook of them selling a piece of furniture I see a chair from my storage room in the building in their apartment, can I enter and take my property back or do I need to call the police? Or what do I do in this situation... first time this has ever came up.
