Running a legal massage parlor without getting charged or raided

Hi, I'm looking to establish a chain of massage parlors in Pune. It has come to my notice that due to explicit activities being conducted in a majority of such parlors, the local police have conducted raids and barred many owners for misconduct. Many such parlors are also charged for human trafficking and selling services of that of a brothel under the veil of a massage parlor. How can I protect myself and my establishment from such raids? I aim to run a clean center for ailment and recovery of those who perform heavy activities in their daily life such as going to the gym or sitting at work for long hours. How can I make sure that such activities are not conducted in my establishment? Even if I were to sign agreements with my masseuses upon hiring them and another one with the clients before their massage, how can I protect myself and my establishment further in case they are busted in one such illegal act? Since installing a camera in the massage room is not viable / legal, how can I completely safeguard myself and the establishment from being held responsible? We do not encourage such acts.
