A New Hampshire man is being held on over 200 counts of sexual assault-related charges after he allegedly kidnapped and held a teenage girl captive for almost a year.

Nathaniel Kibby, 34, was held without bail after being charged with 80 counts of aggravated felony sexual assault and another 80 charges of sexual assault, New Hampshire Assistant Attorney General Jane Young said Wednesday, according to ABC News.

Kibby also faces 40 counts for other crimes, bringing the total charges against him to 205.  

In Oct. 2013, he allegedly used a Taser to kidnap a 14-year-old girl, according to court records obtained by ABC News. He held her captive at his Coos County home and repeatedly sexually assaulted her for the next nine months, at one point using an "anti-bark shock dog training collar" to keep her quiet, the court documents allege.

Kibby is also accused of gagging her, bounding her wrists with zip ties and taping her eyes shut before placing a motorcycle helmet over her head. On another occasion, he allegedly lay on top of the girl, placed a gun in her hand and said it would be better if she shot him instead of telling police what he had done.

The defendant is scheduled to be arraigned in early January. A lawyer for Kibby, Jesse Friedman, said, "We maintain Nate Kibby's innocence," The Boston Globe reported.

In July 2014, the same month the teenager returned home, Kibby allegedly made the girl clean herself in an apparent attempt to destroy DNA when he learned of a missing persons report, the newspaper reported.

It was not immediately clear how the girl, now 16, returned home on July 20. Her name was originally reported when the situation was just a missing persons case. But now that she is the alleged victim of sexual assault, her name is being withheld.

"We recognize that the victim's identity is known, and I know we cannot un-ring the bell now," Young told The Globe. "While we can't un-ring the bell, we don't have to keep ringing it either."
