LINCOLN, Neb. (AP) - A former Lincoln day care worker accused of sexually assaulting children has pleaded not guilty to seven federal counts.

U.S. District Court records show 26-year-old Titus Miller entered the pleas Wednesday in Lincoln. The charges include sexual exploitation and production of child pornography. A trial date wasn't set.

State prosecutors have charged him with four felony counts of child sexual assault. A court document says the crimes involve four children and occurred between July 31 and Sept. 16.

The FBI established a website to help investigators identify any children who may have been victimized by Miller. The site's home page says Miller worked at Playful Painters Child Care and says he "allegedly sexually assaulted and covertly produced sexually graphic videos and photographs of his victims."
