Unfortunatly you can be arrested even though you returned the property and this is clearly a civil not criminal matter. In Florida companies like the one you mentioned have been able to convince Leo's and prosecutors to arrest and file theft or conversion charges under similar circumstances.
Make no mistake a large number are not prosecuted because the state attorneys feel like these companies are "gaming" the system by using the criminal courts as civil collection agencies. I would explain next time you've retained an attorney who will be happy to speak to the detective assigned to the case.
Save yourself some aggravation retain an experienced criminal defense attorney in your town to help you.
You should report this to the agency regulating collection agencies in your state. You may want to talk to a personal injury or debt relief lawyer about this (but not about bankruptcy). In Wisconsin it is a crime to threaten someone with criminal prosecution to collect a civil debt. That is what this sounds like, but I do not know that the law is the same in Florida.
You may still owe the money but you haven't described any crime.

It is possible you could be arrested, but this really is a civil matter. I'll give you two free bits of advice. First, get an attorney that will fight for your rights now before this becomes a criminal matter. Second, save ALL receipts and other papers related to this matter as it will become very useful for either a civil or criminal matter. You may also want to call the consumer protection agency to report those harassing calls, but talk to an attorney first.
The theft statute is very broad and makes it a crime to deprive somebody of their property, but also to "attempt" to deprive somebody of their property, and even to "temporarily" deprive somebody of their property. So if you were even late bringing the property back, technically, you violated the statute. You should hire a lawyer to try to negotiate this matter so that you are not charged with a crime. You should call my office about this at the link attached.
Yes, you could face criminal charges out of this, but it is clearly more of a civil issue than a criminal matter. Based on the threatening nature of the telephone calss, you need to hire an attorney.
Based on the limited information you provide it is hard to provide an answer. Generally, it is unlawful and a violation of the fair debt collection practices act to threaten criminal prosecution to collect a civil debt. However, Florida does have a statute which addresses the failure to return rented property. My gut feeling is this is a collection agency acting inappropriately however you should still consult with counsel.
