i think you need to bear in mind, it's a personal statement - you need to write about something personal. does human rights relate to your own goals or future career? if it doesn't, i agree with Panda; write about something else.
the situation in India may be interesting to you, but how is it relevant to UK law? what do you know about the law in the UK? is there anything ongoing that you're interested in and can demonstrate sufficient understanding?
bearing in mind also that 'human rights' in itself is far too broad; it's like saying 'i have an interest in tort law', could mean almost anything. if you decide to mention human rights, you need to pick one and give examples.
