Not all countries have strong copyright laws. This is unfortunate. In the U.S. and Europe, there are legal actions you can take. In India (I may be assuming too much here), I have no idea. I suggest contacting an attorney and simply ask a few questions. In the U.S., this is a criminal act and any civil action can result in recovering payment for damages plus punitive. In India, you may have some of the same options.
Now onto the DMCA:
The Digital Millennium Copyright Act (DMCA) is a U.S. Copyright law that can be used to your advantage. It is in cooperation with the World Intellectual Property Organization (WIPO). I suggest at least looking at the linked to Wikipedia page briefly.
With Google, you can file a complaint using the DMCA Dashboard. This may require a Google account. You can find out a bit more of what Google does here: Google - Legal Help: Digital Millennium Copyright Act.
This option not only files the complaint with Google, but makes this complaint a part of a larger Chilling Effects network. But there is no legal action taken with a Google DMCA filing.
Again, I do not know what options you may have in your country, but I did find this with a complaint form link on the bottom of the page, which may help.
Some websites offer advice on how to contact the owner of the other site. I do not recommend this in your case because it is so blatant a violation, you may be better off simply filing a complaint rather than tipping off the violator.
