Owatonna High School was in lockdown Monday

Offensive or racist comments on social media are being blamed for a disturbance at Owatonna High School Monday that resulted in a lockdown.

Police responded to a large group of students shouting and being disruptive in the commons area and gymnasium.

School staff ordered a lockdown, but officers say some students were uncooperative.

One juvenile was arrested for assaulting an officer, another was taken into custody for obstructing the legal process and a third student was cited for trespassing.

There were no reports of injuries. Investigators believe the incident may be connected to racist comments posted on social media by white students.
