Request for Legal Assistance Regarding Harassment and Loan Repayment Issue

Dear [Recipient's Name], I hope you're doing well. One of my friend's families is currently facing a difficult situation, and I would greatly appreciate your expert advice on how to handle it legally. My friend’s son-in-law took a business loan from his friends and colleagues, but unfortunately, his business faced a loss, and he is now unable to repay the loan. As a result, individuals who lent him the money are now visiting my friend's home (his father-in-law’s residence) and demanding repayment. This is causing significant distress and damaging their reputation. My question is whether it would be possible to obtain a court order that prohibits these individuals from contacting or visiting my friend's home to demand repayment. Additionally, if someone were to come to the house or make contact, could my friend call a local police officer and inform them of the court order, seeking their intervention? Any guidance you can provide regarding this matter would be greatly appreciated. We're hoping to resolve this issue in the most efficient and legally sound way possible. Thank you in advance for your assistance.
