North St. Paul police officers were called to the suburb's North High School last week when an armed student assaulted a school resource officer, authorities said.

The resource officer was asked to question a student on Nov. 9 after receiving tips that the student had a gun. When the student was asked about the gun, the student began "violently assaulting school employees and our school resource officer," according to a city news release sent this week.

The student refused to hand over the gun, which was loaded, according to the release.

Additional officers arrived and were able to control the student and take the gun.

The student was arrested and charged with numerous crimes, including fourth-degree assault of a school official, possession of a dangerous weapon on school property, possession of ammo/pistol/assault weapon as a minor and interfering with a peace officer.

In a separate incident, South High School in Minneapolis went on lockdown Monday after multiple fights broke out in the common area and in a bathroom. There were no weapons involved, the Minneapolis school district said.
