DENVER (AP) — Authorities say Aron Ralston, who gained widespread attention when he cut off his forearm to free himself after becoming trapped by a dislodged boulder in a Utah canyon, has been arrested in Denver over allegations of domestic violence.

The 38-year-old was booked Sunday on charges of assault and wrongs to minors. Police spokeswoman Raquel Lopez tells The Associated Press she can't release any details until she speaks with a domestic violence detective.

Ralston was hiking in 2003 when he became trapped by a boulder and 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."

Booking documents don't indicate if Ralston has an attorney. He's scheduled to appear in court Monday.
