At least 61 people were arrested Sunday in Chicago after an unruly crowd fought with officers, and jumped on police vehicles at the end of Independence Day celebrations in the city, according to reports. 

Those arrested – mostly young adults and minors – were among the hundreds of people who flooded the city's downtown streets. Bottle rockets were fired at officers during the unrest, one of whom was hit near the ear, police said. Another officer was injured during a scuffle with a suspect. Others in the crowd resisted orders to disperse, FOX 32 Chicago reported.

Suspects were arrested for offenses including battery, disorderly conduct, and resisting arrest, a police spokesperson told the station.

"Sunday night was a disaster," said Ald. Brian Hopkins, according to Chicago's WBBM-TV. "We had massive chaos and mayhem downtown. We had guns in backpacks. Guns in pockets. A large number of firearms present."
