Jesse Andersen, 35, was going to work early Thursday at the Hyatt Regency Hotel when he was set upon by four males and a female, between the ages of 15 and 25, who grabbed his iPod and punched him when he tried to get it back, the Chicago Sun-Times reported.
"He was just sitting there on the train, listening to his iPod," Corgan told the newspaper. "They obviously set him up to rob him."
Corgan, 44, who gained fame as a founding member of Smashing Pumpkins, said via Twitter: "My brother Jesse just finished an interview with a 2nd tv station about being mugged. The bad guys picked the wrong kid to [expletive] with!"
