south-central Idaho man accused of repeatedly raping and beating a woman and holding her prisoner for 18 months in a booby-trapped home has pleaded not guilty.

The Times-News in a story on Friday reports that 36-year-old Oscar Ayala-Arizmendi made the plea in 5th District Court.

He's charged with first-degree kidnapping, rape and possessing a controlled substance.

Authorities say the woman escaped from the house in Buhl on April 8, and made a report on April 26. Ayala-Arizmendi was taken into custody May 13.

Authorities searched the house near U.S. Highway 30 and reported finding chains and locks mounted to walls and floors, chains on exterior doors, a handgun, and an electrical wire system intended to shock anyone trying to escape.

A trial is set for Nov. 17.
