Also, a nursing student who was a victim in the attacks is talking about his attack for the first time. The man says he has been emotionally scarred by the incident.
The three teens face charges including felony battery and/or mob action.
A judge gave three of those arrested a bond of $200,000 or more.
"I couldn't expect that it would happen to me," said the victim. "There were more than ten."
Still shaken by the attack, the 20-year-old nursing student from the North Side asked that his face not be shown as he talked about the June 4th attack he suffered at the hands of a group of teens.
Friday morning, the teen the man said beat and robbed him of his iPhone, Derodte Wright, 18, appeared in court with two others.
"We're going to prosecute them to the fullest extent, because it's so important here for the citizens here in Chicago to know that they are safe and that we are here for public safety," said Cook County State's Attorney Anita Alvarez.
Police say Trovolus Pickett, 17, not only helped Wright attack the nursing student, but also teamed up with others to rough up a 68-year-old Seattle doctor minutes earlier, before going on to rob a Japanese tourist of his iPod.
"It hurts, it hurts, considering that my son has never been in trouble, never been in trouble with the law, and then the outrageous bond up to $250,000, like, 'OK, we're gonna make an example,'" said Tonia Rush, Dvonte Sykes's mother.
Meanwhile, the mother of Dvonte Sykes, 17, says she her son did nothing wrong, but the 17-year-old Chicago Public Schools student, stands accused of robbing a man of his camera and being part of the mob that tried to rob a suburban man of his scooter.
"As long as you look around and you're aware of things, I don't think that it's too bad," said shopper Johanna Forsgren. " You can't be afraid of being downtown just because of something that has happened."
Statistics show that robberies have increased this year in the downtown Near North police district, getting the attention of those in Chicago's fragile tourism and convention trade.
"We understand and we have complete faith in the police department that they are working on this and that they will fix it," said Megan Risch of the Chicago Tourism and Convention Bureau.
The mother of Dvonte Sykes says the bond was set too high. The Cook County State's Attorney's office says they believe the bail set by the judge is fair considering the crime. Wright, Pickett and Sykes are due back in court on June 24th.
Two 16-year-olds are also charged in connection with the attacks.
