Police say Hutson fled the scene and was taken into custody in the college parking ramp by Bloomington police. At the time of the arrest, a handgun was recovered from Hutson's backpack.

Police told 5 EYEWITNESS NEWS they could not confirm whether the gun was ever inside the school building, or if it was loaded, or whether any ammunition was found during Hutson's arrest.

A Normandale student told 5 EYEWITNESS NEWS she was in the classroom where the assault happened. She asked to have her identity protected for safety reasons.

"Gavin Hutson said something underneath his breath to another student and the instructor overheard it," the student said. "The teacher told him it was disrespectful and asked him to stay after class and it was after we all left that the assault then happened."

The classmate of Hutson also said no one in the classroom thought the issue was going to escalate into violence and the instructor - whom she identified as Nancy Claycomb - seemed to also be calm as class was dismissed.

"Nancy had just asked to him to stay back and talk about what had transpired," the student said. "When I heard what happened I was really surprised because Gavin seemed like a really nice guy and there did not seem to be a big issue brewing."

Another Normandale student, Desiree Hendricks, told 5 EYEWITNESS NEWS she was on a break from her psychology class when she noticed a lot of commotion down the hall.

"I could see police running up from the parking ramp and I could tell they were in a hurry," Hendricks said. "And then they rushed by us toward the second floor where the class was and it was a little chaotic and mass worry because we did not know what was going on."

The instructor was transported to Fairview Southdale with injuries that were not considered to be life-threatening.

An additional victim - a 23-year-old man - was injured while Hutson fled the building, according to a release. He was treated at the scene.

Hutson is currently being held at the Bloomington Police Department on probable cause third-degree assault, fifth-degree assault and possession of a firearm without a permit.
