At least 10 patrol cars went to the scene.
“It was a very chaotic scene,” according to Drummond, who said the fight erupted as the ceremony was ending about 11 a.m. and then moved outside.
Officers quickly restored order, Drummond said. More than the eight arrested were involved in the fight, and the initial heavy police response came amid a call, which turned out to be false, about shots fired, he said.
No students enrolled at the school were involved, school district communications officer Roseann Canfora said in an email.
The school was put on lockdown and parents began arriving to take their children home.
Johnson said the quick police response was important amid heightened concerns about school security.
“It is embarrassing that parents during a kindergarten promotion cannot control themselves, and what we tried to do was respond significantly,” he said.
Any parent involved in the fight should be banned from the building, Johnson said. “We’re not going to have people coming into our schools, being disrespectful, fighting,” he said. “So I support them being hauled off.”
