Two Pittsburgh Police officers from Zone 5 were out on regular patrol when they witnessed a group of people chasing a male on Collier Street near Idlewild Street just before 2:25 a.m.
When they approached the group to ask what was going on, they became confrontational. A female punched one of the officers in the face and other males joined in the assault where OC spray was deployed. Officers from Zones 5 and 4 were called for backup.
Three people were arrested, two juvenile males and an adult female. All three were taken to the hospital per protocol to be medically cleared. They face charges of Aggravated Assault, Resisting Arrest, and Obstructing.
The officers were treated by EMS on scene for OC exposure. No one received serious injuries.
Police were told the incident originally stemmed from a domestic dispute, for which a separate report was taken.
Police are investigating.
