CHICAGO — A new grand jury indictment accuses a 53-year-old suburban Chicago man of video recording minor boys having sex acts performed on them.

A statement from the U.S. attorney’s office in Chicago says Douglas A. Willis, of Naperville, pleaded not guilty Tuesday to producing child pornography and to conspiracy to produce child pornography. Each of those two counts carries a minimum 10-year and maximum 20-year prison term.

The indictment alleges that Willis and an unnamed co-conspirator recruited boys under 18 in exchange for money. It also says the boys would be given drugs and alcohol in an attempt to reduce their inhibitions. The court filing alleges that the conduct occurred between 1993 and continued at least until August 2001.

Court filings did not include the name of an attorney for Willis.
