A Michigan grandmother allegedly helped her granddaughter beat up a fellow student at an elementary school, according to officials.

Mt. Morris Township Police said the grandmother and her granddaughter were dropped off at McMonagle Elementary School on Thursday for a behavioral meeting, WNEM reported.

The grandmother saw another girl her granddaughter was not getting along with, so she and her granddaughter followed the girl into a bathroom, where the grandmother is accused of holding down the girl while her granddaughter punched her.
