I assume your Park has rules that say if your tenants cause disorderly conduct, noise violations, etc of the like where police intervention is needed and citations made then I expect this is a basic violation of your rules and can be used to terminate the lease.
Get a copy of the police report(s) and follow the eviction process in accordance with your state and county laws. If you have not gone through this before then an attorney would be good to guide you.
Curious how well you screened this tenant...this is key so you don't turn your MHP into a trailer park. Too much of this will cause your good tenants to move out, so get on top of it or it will get on top of you.
