How do we get Police to provide protection to enforce the permanent Injunction i have from the Court

My father had purchased a Revenue property in 1991. The surrounding properties were also revenue. BDA started reconvening the properties and expanded the road adjacent to our neighbours property. 15*20 feet of his land went into road. but he encroached 15*20 feet into our property. BDA did not consider the land lost due to expansion and allotted him sale deed for the land. As complete 30x80 was not available for me as per my revenue sale deed, BDA allotted me 2 parts. Part 1 consisting of 30*50 and part 2 consisting of 15*20 feet. My parents did not oppose this encroachment and were ok with the land allotted to us. Seeing that we were'nt strong and as the land was vacant, he further encroached into the part 2 of our property. He filed an injunction suite against us in 1994 and this was for his property. We had no impact nor were bothered with this as it was for his land. We filed an injunction suite in 1995 against them for our property (both part 1 and part 2). We were granted permanent Injunction for both the parts in 2011. He appealed to High court and this case was dismissed in 2022. But when we went to construct a fence to our property, he with some local influence is torturing us and not allowing us to enter our own land. Police quietly slipped of saying that it is not in their power to involve in property related issues and this needs to be dealt in court. How do we proceed? We have already spent a lot of money on court procedure and it has taken 30 years to get the permanent injunction. We are quite powerless as the other party has a local politician supporting him.
