The number of victims linked to an accused cyberstalker from Detroit has increased to 18, and the defendant now faces additional charges of producing child pornography.

James S. Allen was charged last year with cyberstalking 10 local women and girls, but a new federal indictment puts the number of victims at 18 and includes new allegations of producing child pornography.

FBI investigators claim Allen targeted girls as young as age 14 and then used Internet-related technology to contact and harass them. They contend his goal was to get them to send him nude pictures of themselves.

Allen was arraigned on the new charges Monday before U.S. Magistrate Judge H. Kenneth Schroeder.
