An 18-year-old man was charged along with seven teenagers who were charged with mob action following a series of muggings carried out Saturday night by groups of attackers, including one that left a visitor from Michigan hospitalized with a broken jaw.

In the first attack, a group of young people beat and robbed the 40-year-old man in the 500 block of North State Street just before 10 p.m. The victim, who was in Chicago on business, according to a relative, was treated for a broken jaw at Northwestern Memorial Hospital.

Mitchell Coradarrowe, of the 5900 block of South Indiana Avenue, was charged as an adult with felony aggravated battery and mob action, according to police.

The juveniles, ranging in age from 13 to 16, have each been charged with three counts of mob action in connection with the attack.

A second attack, which police believe to be unrelated, occurred about 30 minutes later near the Lake/State Red Line station in the 100 block of North State Street. A couple was accosted by an unknown number of suspects near the Chicago Theatre. A male victim suffered minor injuries and was also treated at Northwestern.

Police received a report of a third attack near Navy Pier, but police couldn't provide the exact time of the attack.

The attacks occurred as city officials were preparing downtown for the upcoming festival season, including Lollapalooza, The Air and Water Show and the Taste of Chicago, which are expected to bring thousands to the city and generate millions of dollars in revenue.
