[mn] Getting My Brother Out My House

[MN] Getting my brother out my house

I let my brother stay with me over 3 months. My landlord found out and he has told me I need to get him out. My brother is claiming squaters rights and won't leave. I hae called the police and they are telling me I need to file an eviction. My landlord is saying that's filing an eviction is not going to work and call the police? I have Pre-Paid Legal (I know now) and they said to call th sheriff's office. I called th sheriff, who told me to call housing, who told m I need to file an eviction. I'm in a spiral and I don't know what to do.

Please help
