Colorado authorities on Monday said they have found a 14-year-old girl who was last seen 10 days ago and that she took steps to avoid being found. 

Chloe Campbell was found around 5 p.m. at a residence in Thornton, a suburb located about 26 miles from Boulder, Boulder Police Chief Maris Herold told reporters during a news briefing. 

"While investigators continue to believe that Chloe ran away, there is an ongoing investigation about where she was and what occurred while she was separated from her family," Herold said. 

Campbell was released to her family and will be medically evaluated, police said. Few details were released, but authorities said they do not believe she was held against her will.
