The school superintendent in Easthampton said disciplinary action has been taken against a student who allegedly bullied others through social media.
This comes as Massachusetts Attorney General Maura Healey investigates incidents at Easthampton High School.
Earlier this month, the School Committee voted to ban students from wearing the Confederate flag.
Later, a student posted on Instagram the words "Make Easthampton Great Again" with photo-shopped images of students and the principal holding guns in front of a Confederate flag.
Easthampton Superintendent Nancy Follansbee said the post is serious, but conflicts at the school are not escalating.
"We have addressed all disciplinary issues with appropriate discipline," Follansbee said. "And we're monitoring the safety and the climate of our high school."
Natalie Poirier, a parent of two children in the high school, said one of her kids was targeted in the Instagram post. She has pulled her children from the school.
Poirier said lawyers from the Attorney General's office came to her house on Monday and interviewed her, her children and other students for seven hours.
The AG's office confirmed it is investigating incidents at the high school, but won't comment on specifics.
