A 52-year-old man has denied allegations that he videotaped female co-workers in various stages of dress in a northeast Nebraska company locker room.

Authorities say former Solbar employee Larry Wolf, of Dakota City, pleaded not guilty on Monday to two counts of unlawful intrusion.

Court documents say Wolf was arrested in July after a technician who was working on Wolf's personal computer found a file that contained about 60 video clips of the women's locker room at Solbar, a soy protein production company in South Sioux City.

A police affidavit says images on the computer showed Wolf's tattoos as he placed the camera in the locker room.
