Brazilian authorities detained an Arab who ran a Web site forum that could be linked to terrorists and included anti-American statements in Arabic, a prosecutor said Tuesday night.
The Arab resident of Brazil was not identified and a court ordered his release after police investigated, federal prosecutor Ana Leticia Absy said in a statement.
Absy said Brazil police were alerted to the presence of the closed Web site by the FBI, obtained judicial permission to investigate it and concluded it could be connected "to a terrorist group."
