Life Threat By In Laws and relatives after MCD Granted

Hi, I have recently got a mutual divorce decree which says everything has been settled like Istridhan, dowry and jewelry articles and alimony and maintenance has been paid in one time settlement. No Relation is there between us and we cant claim anything further or file any cases on each other. But Even after that I and my family members are getting life threat calls and messages from the relatives of my ex-wife to return small items like suits and sarees presented to my relatives, dinner set, lahanga etc for which my wife refused to claim during our settlement in front of judge. Please tell me what should I do to avoid this trouble. every second day we are getting calls that they will send police to our house with search warrant, send all of us in jail and would get us beaten and killed by some killers on contract. my wife and her family members are not saying anything in such regard but its her uncle and other relatives troubling us. pls suggest.
