Thousands of people on Thursday formed a human chain around Central Park in Delhi's Connaught Place area to protest the increasing number of rape cases and raise awareness about the issue, the Delhi Commission of Women said. The human chain was formed as part of the DCW's "Rape Roko" campaign, which it had launched after the brutal rape of an eight-month-old baby in January. Since then, the commission has been staging programmes to raise awareness on the issue.
