(AP) — A Fremont man has been given 40 to 50 years in prison for sexually assaulting a child and producing child pornography.

The man was sentenced on Monday in Dodge County District Court. He had pleaded no contest after prosecutors dropped other charges, including five counts of incest. The Associated Press is not naming the man, in order to protect the privacy of the child.

Prosecutors say that on Nov. 17, 2011, the man used hidden cameras to make child pornography. Prosecutors also say the man sexually assaulted a child more than 30 times between November 2010 and May 2013.
