Thomas Insley, 16, was attacked near Ashland and Jonquil Terrace in the city's Rogers Park community on the North Side, blocks away from his house.
The victim's father Alan talked about the attack Tuesday night.
"He said he was choked, I found out later not right on the sidewalk but pulled into the alley by three or four other people," said Alan Insley.
Alan Insley says his son has a concussion, broken nose and several loose teeth. He had money and his iPod stolen.
"He woke up with another guy bringing his wallet back," said Alan Insley.
Thomas Insley is a junior at Whitney Young, a Chicago public school on the city's near West Side.
Insley takes public transportation from school to his far North Side neighborhood. His brothers and father are alumni of Whitney Young.
On Tuesday, his father spoke about the need to improve student security.
"I'd like see more effort in Chicago toward safety for children," said Alan Insley.
While the family has lived in Rogers Park for 16 years, Insley's father said that after this incident, they would consider a move.
"We'll have to see what we do - it'll depend how he feels sometimes kids don't recover that well from being attacked - people don't - and if he's uncomfortable we may move," said Alan Insley.
Despite his injuries, Thomas is expected to be released from the hospital. He will need to see a dentist about his teeth.
Police continue to search for the suspects.
