Anoushka Shankar, daughter of legendary sitarist Ravi Shankar, has thrown her weight behind an online campaign demanding an end to crime against women, in the wake of the Delhi gangrape.

The 31-year-old sitarist has invited one billion women and those who love them, via the website Change.org, to walk out, "Dance, rise up, and demand" an end to this violence this Valentine's Day, February 14.
