The Gainesville Police Department broke up a group of fighting juveniles Saturday near Waldo Road.
Around 5 p.m., 18 patrol units arrived at the 900 block of Northeast 14th Street to find about 35 people fighting, said Erica Doll with the GPD's Public Information Office.
There were no weapons at the scene, but people were using rocks and sticks, Doll said.
Most of the people involved were juveniles, and three were arrested, she said.
A male juvenile was arrested for aggravated battery because he hit another juvenile in the head with a brick.
Another male was arrested for resisting arrest without violence, and a female was arrested for hitting a person in the face in front of police officers.
Doll said police still do not know why the fight was started.
