An adventurer, whose story of cutting off his own arm after getting it trapped in a canyon became a best-selling book and film, has been arrested on suspicion of domestic violence.
Aron Ralston, 38, was arrested alongside a woman Vita Shannon accused for assault.
The Denver Police Department has not provided any more details of the alleged incident.
Dalston is being held at a jail in Denver and is due to appear court to face the charges. Under Denver state law, a suspect in a domestic violence case cannot be granted bail before he sees a judge.
Ralston became famous worldwide in 2003 after he was forced to cut off his own arm with a pocketknife after it became lodged in a boulder in a Utah Canyon.
The experienced hiker, who trapped for three days before taking the decision to cut off his arm, wrote a best-selling book about his experience in 2004 entitled Between an Rock and a Hard Place.
The story was then adapted into a Hollywood film starring James Franco and directed by Danny Boyle.
The film, 127 Hours, went on to be nominated for six Oscars, including Best Picture and Best Actor for Franco's portrayal of Ralston.
