At least 61 people were arrested Sunday in Chicago after an unruly crowd fought with officers, and jumped on cop cars 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.

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

A man fired into a crowd of revelers around 1:30 a.m., striking Patrina Wines, who took over as commander of the 15th District last year, the Chicago Sun-Times reported. A police sergeant also suffered a graze wound to the leg. Wines and the sergeant did not require hospitalization.

Chicago Police Superintendent David Brown said both officers are going to be "all right."

"As you know, there’s been a lot of large crowd gatherings tonight, a lot of celebratory fireworks going off, kind of spontaneous," Brown said at a news conference. "They were dispersing a crowd when they heard shots and felt pain."
