Police say they arrested a Missouri woman after she allegedly threatened to hit a school principal and made death threats during a dispute at a school.

The Livingston County Sheriff’s Office says the 34-year-old woman, who has a child at the Chula School, became enraged this week during a meeting with a school official.

That’s when the trouble began.

After she was asked to leave, she reportedly pulled a phone out of the wall, tried to hit the school principal and threatened the lives of school officials.

Sheriff Steve Cox says staffers restrained the woman until deputies arrived. She allegedly continued to resist arrest and assaulted and threatened the deputies.

Authorities did not say what prompted the woman’s anger.
