Student housing: dealing with one student trying to break lease

[Logan Koch]

Dealing with an issue of one tenant within a student housing property wanting to break the lease and move out. I had a parent call me saying their student and another student living in the property were in a verbal argument, where the parents student was threaten by the other. They are moving him out breaking the lease and asking for a full refund for the fall semester. 

We have in our lease the ability to evict a student causing a hostile environment. Which based on the story I'm getting, this would be a good option. My question is since they have already moved their student out and are asking for a refund what is the best course of action? Legally is this a situation a lease can be broken, and returned the rent they have paid?

We do not want any hostile situation to come about in our properties, and would step in and evict a tenant causing a hostile environment. However, it seems they are set on getting a refund and not returning to the property if an eviction would occur.
