Demolition of property during court case by the tenant

We have filed a court case against a tenant who tried to grab the property during the court case illegally FDP is in progress however court commissioner is yet to be appointed, Tenent is likely to destroy the walls which will affect our old building. Is there is a law to prohibit or what action can be taken to avoid him from destroying anything till FDP take place. We need advice at the earliest since the court vacation is going to commence soon.
