Students at Newton North High School in Newton, Massachusetts, were seen waving a confederate flag in the school parking lot.
The video, taken by a student, shows students driving a car around the parking lot and waving the flag outside the car window.
According to the Boston Globe, both Newton Police and the school are investigating the incident.
The school sent a letter to parents on Wednesday and called the incident "deeply troubling."
At this point the school has identified the students who were involved but has not released their names publicly.
Mayor Setti Warren issued the following statement today:
“Waving the Confederate flag on Tuesday at Newton North High School was absolutely unacceptable. We need to acknowledge that the Confederate flag is a hurtful symbol to many in our schools and our community.
While we have initiated work with faculty, administrators, students and with members of the community based on events of the last year to make Newton a more welcoming and inclusive city, it is clear to me that we have a lot more work to do.
Today, I had the opportunity to speak with students as well as visit Newton North. Next week I am going back to the school to meet with students, so that we can work together to promote empathy and understanding.”
