A group of Christian students has donated $100,000 to the city of Atlanta to help fight human trafficking.

The money will be used to help the Atlanta Police Department combat sex crimes.

The students donated the funds at a three-day conference in Georgia's capital city known as Passion 2012.

The conference is part of a movement among collegiate Christians who unite in worship and prayer for spiritual awakening in their generation.

This year's event drew 42,000 students from all 50 states and 30 countries to the Georgia World Congress Center.

The focus of this year's conference is freeing the enslaved people around the world.

"There's 27 million slaves in the world today, that's men women and children forced to work," Bryson Vogeltanz, with Passion 2012, told Atlanta television station WXIA. "The sex trafficking issue is here in Atlanta and all over the world."
