Legal Question in Criminal Law in Ohio

In Ohio this is a landlord tenant law issue not a criminal law issue. Relations between landlords and tenants are governed by the Ohio Landlord Tenant Act of 1974. Part of that Act is Ohio Revised Code 5321.15. That part of the Act prohibits a landlord from engaging in what are called "self help" evictions, meaning an eviction without going through the statutory eviction process laid out in Ohio Revised Code Section1923.04.

That section of the law provides for actual damages and attorneys fees if you can show that the landlord locked you out without a hearing before the court after filing an eviction. But it isn't something that involves the police. You would have to file the lawsuit. You could sue in small claims court. Because the law provides for attorneys fees it might not be that hard to find an attorney to take your case. This is especially true if you have anything in writing from your ex like an email in which he admits what he did or in which he threatens you in regard to your belongings.
