Ralston, who cut off his forearm to free himself after becoming trapped by a dislodged boulder in a Utah canyon, has been arrested in Denver for domestic violence. He was booked into the Downtown Detention Center on Sunday, Dec. 8, 2013 on charges of assault and wrongs to minors. Ralston was hiking in 2003 when he became trapped by a boulder and was forced to cut off his own arm to free himself. He went on to detail his struggles in a book, and his story was later adapted into the movie ""127 Hours."" (AP Photo/Denver Police)"
