ANN ARBOR, MI - An argument between two moms escalated into a physical fight Monday morning at an Ann Arbor middle school, police said.

The women started arguing around 9 a.m., Feb. 10 inside Slauson Middle School, 1019 W. Washington St., Ann Arbor police said.

The disagreement stemmed from the mothers’ children not getting along, police said. Verbal sparring turned into a physical altercation around 9:20 a.m., police said.

The fight was during a dance recital for National African American Parent Involvement Day, police said, but the race of either parent was not known.

The fight was not racially motivated, but the school was placed in a “soft lockdown,” Ann Arbor Public Schools spokesman Andrew Cluley said.

“Due to an unfortunate conflict between parents (Monday) morning, the Ann Arbor Police Department responded to Slauson to support the situation," Cluley said in a statement. "Out of an abundance of caution, the school was placed in a soft lockdown to ensure no students would be in the hallways while the (police) were responding. We appreciate the quick response and support of AAPD.”

Cluley added that the school routine resumed quickly after the police response, and that the rest of National African American Parent Involvement Day went smoothly.

Both parents were not arrested but are being interviewed by police, and the investigation is ongoing. No further details were immediately available.
