(CBS) — Chicago police made several arrests Saturday evening following another “wilding” scene instigated by young people along the Magnificent Mile.

Photographers shot chaotic video of police officers and vehicles swarming Michigan Avenue near Huron and detaining several young people around 7:30 p.m. Some of the disturbance leaked onto Chicago Avenue near State Street on a relatively warm night with temperatures in the 50s.

Chicago Police News Affairs confirmed officers arrested “a number of offenders” and said charges were pending. Details weren’t available.

But community activist Andrew Holmes, who happened to be shopping with a relative in the upscale retail district, described a scene in which hundreds of young people misbehaved, with some of them harassing and attacking people on the street.

“They assaulted a Chicago police officer who was on a mounted horse. And all of a sudden, they assaulted the citizens walking the streets – just normal citizens shopping, enjoying the weather,” Holmes told CBS 2’s Chris Martinez. “I caution those parents if their child has been arrested … You need to think about your child. Just don’t say the Chicago police picked on your child, when we watched all the assault going on, especially by teen women.”

Chicago’s Michigan Avenue and nearby retail strips were beset by numerous wilding, or “youth mob,” episodes the past two summers.

The phenomenon continues in Chicago and its suburbs. In February, a disturbance broke out at Ford City Mall after a meet-and-greet appearance by the boy band Mindless Behavior. A mall official blamed groups of “older  youths” and said it had nothing to do with the event.  (read more with video)
