It is illegal. If police is arresting someone for something illegal and Television News channels are also reporting it as illegal, then its definitely not allowed. G.B Road is working with over 1000 sex workers working in brothels daily as quoted from Wikipedia non-editable summary. You are so desperate in proving me wrong, that you don't see the main point of your own post which saddens me. Are you able to read and write in English properly? Or are you just copy pasting what other people in this thread are posting?

Well. I think you should rather question your own mental capacity for understanding and consider whether you are just being stupid about it.
The point is that prostitution is not illegal. But it is illegal to run a business around it and advertise it. Do these establishments advertise themselves publicly as brothels offering such services. Do they put up a huge board announcing their establishment as a brothel or the rates for everybody to see? If they are not doing that, it becomes a grey area. Everybody in Delhi may know that the street is full of brothels, but Common knowledge is not sufficient to establish guilt of wrong doing in a court of law. Evidence/testimony is required. In order to proceed against organized prostitution, first they need to be caught red handed and a lot of evidence collected, then the police involved needs to be honest enough to take the case to its conclusion. The brothel or business should not have some MLA or MP backing them and influencing the case.
If common public knowledge were enough for police action, here are some things more.
It is common knowledge that most of the politicians across all parties in the country are not only corrupt, but involved in a wide range of crimes including but not limited to abductions, rapes, murders, organized prostitution, human trafficking, drugs peddling and a variety of other illegal rackets.
It is common knowledge that the cine industry in our country is full of black money, underworld connections, organized prostitution and pimping at a massive scale as well as drug abuse and supply chain.
There are places like Ramoji Film city and a other large resorts in Hyderabad where you can hire any of a vast number of actors and other artists from Telugu movie and TV industry to sleep with for amounts ranging from tens of thousands to several lakh's or even crores. It is common knowledge for people in Hyderabad for years now, but is anybody going to take any action on it?
Most if not all of the resorts across the country that corporate's love to hire for their employee outings are also hubs of prostitution. Several years ago, one of the resorts here in Hyderabad that I went to for a employee outing had rooms for hire that cost 5 Lac+ per night. The clientele are politicians and rich business men and one of the managers after pestering by a colleague revealed that the cost of the room includes a call girl. They can apparently arrange many of known names form the Telugu cine/TV industry.
These places don't advertise themselves as brothels, but they make most of their money from this business only.
