Does it have anything to do with losing the property lawsuit?

Legal analysis: No, your lawsuit against the property is a civil dispute, and the legal status of both parties is equal. It's a civil lawsuit, and it won't be sentenced. Detention is a compulsory act, and the public security bureau of the executive organ can only take detention measures against it if it violates the criminal law or the public security administration punishment law. So there's no need to worry.

Legal basis: Article 236 of the Civil Procedure Law of People's Republic of China (PRC). A legally effective civil judgment or ruling must be fulfilled by the parties concerned. If one party refuses to perform, the other party may apply to the people's court for execution, or the judge may transfer it to the person subjected to execution for execution. Mediation and other legal documents that should be executed by the people's court must be fulfilled by the parties. If one party refuses to perform, the other party may apply to the people's court for execution.
