Authorities arrested a woman after she managed to slip past security guards at her child’s middle school and beat up a teacher, leaving the teacher with a concussion and other serious injuries, district officials say.

Lynzina Sutton, 31, was charged with second-degree assault (injury to a school official) and third-degree burglary for her role in the attack, as reported by Syracuse.com.

Sutton went to Lincoln Middle School in Syracuse last week to target a specific female teacher, who officials haven’t named. When Sutton located that teacher in her classroom, police said she punched the teacher in the face multiple times, fracturing her nasal bone and maxillary spine bones.

“These are injuries that you don’t often see in boxing matches, so they’re quite serious,” District Attorney William Fitzpatrick said of the attack.

The teacher received a concussion from the altercation. She was treated at a hospital and later released.

Up to 30 students witnessed the fight, according to Syracuse School Superintendent Anthony Davis.

School officials say Sutton came to the school a day after a disciplinary report was made about her child. The student reportedly lied about her whereabouts during the school day. Before the school administration could address the referral, Sutton came to the school the next day.
