The investigation continues, said Justice Department spokesman Bryan Sierra, who would not say whether more arrests were possible in the case.

Little turned himself in to authorities in California on Wednesday. His arraignment July 12 is set for U.S. District Court in Tampa.

If convicted, Little could be sentenced to as much as five years in prison on each of the charges, Sierra said.

A man who answered the telephone Thursday at Little's house identified it as the location for Maxworld Entertainment. That man would not comment on the charges against Little, referring questions to Santa Monica lawyer Jeffrey Douglas.

Douglas, who did not return calls, sits on the board of directors of the Free Speech Coalition, based in Canoga Park, Calif. The coalition describes itself is a trade association that serves as a lobbying arm and, if need be, legal defender of the adult entertainment industry.

Assistant Attorney General Alice Fisher of the Justice Department's Criminal Division and acting U.S. Attorney James Klindt for the Middle District of Florida announced Little's arrest Thursday in a news release that included a copy of the indictment.

The indictment alleges that Little - through the entertainment company - distributed pornographic video films to post office boxes in Florida.

The indictment also alleges that to help promote these films, the defendants used a Web site for the purpose of selling and distributing the films by transmitting over the Internet five obscene video clips as promotional trailers.

The news release states that prosecutors are seeking forfeiture of the obscene films, the gross profit from the distribution of the films and all property used in connection with the alleged obscenity crimes, including Little's residence in Altadena.

Federal prosecutors also will seek forfeiture of all the Internet domain names used.
