A lockdown was put in place at Owatonna Senior High School after racist comments made on social media over the weekend led to heated scenes on Monday.
Owatonna police officers were called to the school just before noon on Monday to find a large group of students "shouting and being disruptive" in the gymnasium and school commons area.
A lockdown was then ordered for the safety of students and staff as police handled the situation, according to Owatonna Public Schools.
The reason for the heated scenes were a series of racist comments made on Snapchat over the weekend by some of the school's white students towards some of the school's black students.
FOX 9 said that these posts used the N-word "repeatedly," with police describing them as "hateful."
Owatonna PD said that there were no weapons involved in the altercations at the school, but one teen was taken into custody for assaulting a police officer, another for obstruction, while a third was cited for trespassing.
The lockdown was lifted at 1:30 p.m. Owatonna Public Schools says it will be investigating the racist posts made over the weekend, as police continue to investigate what happened on Monday.
Owatonna Public Schools will be in session Tuesday following a two-hour late start due to the snow.
