(Reuters) - Officials at a Connecticut high school called police after a teenaged student referenced the Islamic State group during a morning recitation of the U.S. Pledge of Allegiance, an attorney for the school district and local media said on Thursday.
The police department in Ansonia, Connecticut in turn handed the matter over to the federal Department of Homeland Security, the Connecticut Post reported, citing local police officials and records of a school board meeting in Ansonia where the incident occurred in October.
The 15-year-old boy, who was not identified due to his age, was not charged but was removed from classes at the school after substituting "ISIS," an acronym commonly used for Islamic State, for the words "the United States of America" during the pledge.
An attorney for the Ansonia Board of Education, Floyd Dugas, said school officials had called police "out of an abundance of caution."
