Backstreet Boys singer Brian Littrell has filed a lawsuit against a Florida county, accusing the sheriffs department of refusing to keep trespassers off of his private beach.Littrell said that to protect the "peaceful enjoyment" of his property in Walton County, Florida, on the Gulf Coast, his limited liability company, BLB Beach Hut LLC, has put up "no trespassing" signs as well as tables, chairs and umbrellas showing where the property line starts on the beach, according to the lawsuit obtained by Fox News Digital and filed in a Florida court recently.He wrote that the efforts have been "in vain, as numerous trespassers have set out to antagonize, bully and harass the Littrell family by regularly, every day, trespassing on BLBs beach, on the Subject Property, in open defiance of the law."The lawsuit seeks a writ of mandamus to require the sheriffs department to keep the alleged trespassers off of his beach.BACKSTREET BOYS' AJ MCLEAN ON WHAT HELPED HIM OVERCOME BEING A CHRONIC RELAPSER AFTER NARROWLY AVOIDING JAILLittrell wrote in the lawsuit that he has been forced to hire security to protect his land and family, and filled out a Walton County Trespass Authorization Form, authorizing the sheriffs department to warn and prosecute trespassers on his property."Despite BLBs numerous requests and the execution of the required forms, the sheriff has refused to come to the Subject Property to enforce the law and remove the trespassers, to charge the trespassers, or to take any action, at all, thereby refusing to do their duty," the lawsuit claims.The lawsuit says that on May 4, a sheriffs deputy spoke to an alleged trespasser on Littrells property, but didnt remove the trespasser or cite them, merely saying that the alleged trespasser "'doesnt agree with private beaches, going on to characterize BLBs insistence that its constitutional rights be upheld as lunacy, to use one of the words used by a deputy of the Sheriffs Department."The lawsuit also claims that on June 5, an alleged trespasser grabbed legal documents related to the dispute out of the property managers hand "and scattered the papers into the wind across the beach."Littrel said BLB also contacted the sheriffs department twice that day regarding the "aggressor," but the department "refused to send any officer.""When BLB personnel contacted the Sheriff for the third time to request an officer again, the 911 operator simply hung up on BLB personnel rather than dispatching the officer that was requested more than an hour prior," the lawsuit states.LIKE WHAT YOURE READING?

This has always been our philosophy and will continue to be moving forward."Littrell told Fox News Digital in a statement: "We bought a home here on this private beach on the Gulf of America in order to be able to vacation in quiet, to be able to enjoy our time without any attention or drama. Unfortunately, we had no idea that there was already a battle which had been happening for years."He said that since buying the home, "we have been targeted by people that dont normally frequent this beach or live in the area. These people, the ones who insist on trespassing in what is actually our backyard, who started this fight have to pass several scarcely populated public beach areas to get to our property."Littrell claimed that the alleged trespassers are "people who believe that anyone who has succeeded and managed to live the American Dream must be bad people. They want it so no one owns anything, and everyone is happy, except it never works out that way."He added, "The really scary thing is we have provided to law enforcement all the things they asked of all the private beach homeowners to enforce the law and they will not bother to do their duty to protect the homeowners. They will not do the job they were hired to do when hired and sworn in under oath to protect the citizens and enforce the law."'CLICK HERE TO GET THE FOX NEWS APPHe claimed the sheriffs department has "come against us and will not do their jobs. They allow people to harass and stalk us and the security people," they hired, adding, "They are MAD that we bought a home on a private beach."
