Multiple police officers were injured on Chicago’s North Side Sunday night as the aftermath of the city’s Pride parade descended into chaos with reports of people jumping on vehicles and throwing bottles. Dozens of people were arrested.

The incident took place in Lakeview around 1:30 a.m. early Monday – 12 hours after the pride parade concluded – with the Chicago Police Department (CPD) saying that officers had objects thrown at them and four firearms were recovered while responding to the rowdy crowds.

CPD says that those arrested were charged with crimes including aggravated unlawful use of a weapon, aggravated battery against a police officer, aggravated assault of a transit employee, and armed habitual criminal, Fox reports.

The arrests came on the same day that violence broke out in New York City after a Pride parade in Manhattan, with the disorder stretching on for hours, according to a series of videos posted online.
