ALLAHASSEE, Fla. (AP) - Authorities have arrested a Key West man on charges he used Facebook to sexually harass sorority pledges at Louisiana State University.

The Florida Department of Law Enforcement said Friday that 27-year-old Mitchell W. Hill also was a suspect in similar cases at schools in Florida and possibly other states.

Hill was arrested Thursday on a Louisiana warrant charging him with video voyeurism and extortion of female students.

Florida authorities said someone using the name "Marissa" and "Lexie" on Facebook claimed to be part of victims' pledging process. The women said he asked them for explicit photographs and taunted them.

Hill's lawyer did not immediately return a call seeking comment.
