Officials from Boston Public Schools are investigating what's being called a "disturbing incident of racism" against Boston Arts Academy students.
The incident happened while the students were at the Clark Terry Jazz Festival at the University of New Hampshire over the weekend.
"We were saddened to learn that students from one of the participating schools received racist images on their smartphones via AirDrop while guests on our campus," a statement from UNH read. "This behavior has no place on our campus and goes against all of our values as a community.
The Boston Arts Academy headmaster said shortly before the students were to perform, some received a racist image on their smartphones sent by people nearby.
"This incident was completely unacceptable," the headmaster said in part in a letter to families. "I am very sorry that our students had their otherwise positive experience disrupted by a hateful act."

Boston Public Schools said it is working with UNH to review the incident.
"There is no place for such hateful and vitriolic conduct in our society," Boston Public Schools wrote in a statement.
