Los Angeles, California (CNN) -- A woman whose group has rescued more than 12,000 women and girls from sex slavery has been named the 2010 CNN Hero of the Year. Anuradha Koirala was chosen by the public in an online poll that ran for eight weeks on CNN.com. CNN's Anderson Cooper revealed the result at the conclusion of the fourth annual "CNN Heroes: An All-Star Tribute." "Human trafficking is a crime, a heinous crime, a shame to humanity," Koirala said earlier in the evening after being introduced as one of the top 10 CNN Heroes of 2010. "I ask everyone to join me to create a society free of trafficking. We need to do this for all our daughters."
