(LOUISIANA)--  Federal investigators say pornography accessed via a Louisiana Missouri city computer was not the work of outside hackers.

That means illicit websites were dialed up by someone locally, but authorities have not identified a suspect and no arrests have been made.

City Administrator Bob Jenne said Tuesday that the FBI continues its investigation.

The probe began in February after officials discovered a wireless Internet connection in the water department facility on 30th Street had been misused. In addition to porn, other unauthorized websites apparently were accessed.

Authorities originally speculated that the misuse might have been the work of hackers, but Jenne says the FBI told him recently that the hacker theory is ruled out.
No customer water accounts were jeopardized, and the city has cooperated fully.
