A Waterville man pleaded not guilty Wednesday in U.S. District Court in Bangor to one count of possession of child pornography.

William I. Stewart, 63, of Waterville allegedly possessed child pornography in June, according to the indictment handed up by a federal grand jury Jan. 17.

The images allegedly showed prepubescent children in sexual situations.

The U.S. attorney’s office is requesting that U.S. District Judge John Woodcock order Stewart to forfeit seven hard drives, a desktop computer, a laptop computer, two tablets and and a thumb drive.

He was released Wednesday on $5,000 unsecured bail.

Stewart’s trial tentatively was set for March 5.

Assistant U.S. Attorney Chris Ruge declined to comment on the case. It is the practice of the U.S. attorney’s office not to comment on pending cases.

Stewart’s attorney, Walter McKee of Augusta, did not immediately respond to a request for comment.

If convicted, Stewart faces up to 20 years in prison if it is proven the children depicted were under the age of 12. He faces half as many years if it is proven the victims had reached puberty.
