Three juveniles were arrested Sunday in Downtown Pittsburgh after police say a fight broke out among about 40 people during which pepper spray was used, according to Pittsburgh police.

Officers responded to reports of a large gathering of juveniles at Forbes Avenue and Market Square around 5:30 p.m.

A fight broke out among about 40 people outside. During the incident, police said some juveniles began using pepper spray.

When the officers’ verbal commands to disperse were ignored, they deployed pepper spray to disperse the crowd and restore order, police said.

Police did not say what charges, if any, the three juveniles taken into custody would face. Their ages were not disclosed.

Paramedics set up a decontamination area and treated about 20 people at the scene for exposure to pepper spray, police said.

No one was taken to a hospital, and no officers were hurt, police said.
