DENVER (AP) — A man who cut off his forearm to free himself from a dislodged boulder in a Utah canyon was arrested in Denver on allegations of domestic violence.
Authorities say Aron Ralston and his girlfriend, Vita Shannon, were both booked Sunday on charges of assault and "wrongs to minors." Police say the second charge is used when children are present during an incident but not necessarily hurt.
Police documents say Ralston and Shannon had an altercation with their 8-week-old child present.
Messages left with Ralston's publisher, Simon & Schuster, weren't returned.
Ralston cut off his arm to free himself in 2003. He detailed his struggles in a book, which was adapted into the movie "127 Hours."
Booking documents don't indicate if Ralston or Shannon has an attorney. They're scheduled to appear in court Monday.
