Five people were shot as spectators left a crowded high school basketball game on Friday night in what police called a possibly gang-related attack that sent panicked students running into a snowy street on Chicago's south side.
Five males - three in a serious condition and two critical -were taken from Paul Laurence Dunbar Vocational Career Academy, said Chicago fire department spokeswoman Eve Rodriguez.
Hospital officials said at least three were expected to be treated and released.
"It was crazy. It was like killers on the loose," said Joshua Glaze, 15, a freshman at the school.
The game was in overtime and some students began to leave the building, Glaze said.
A vehicle then drove up and a person or people inside started shooting into the crowd, said Chicago Police Superintendent Jody Weis.
No suspect has been identified or arrested, but the shooting was "isolated" and possibly gang-related, Weis said. Two hundred officers were in the area looking for suspects, he said.
Dunbar freshman Shaneisha Turman, 15, said she saw a silver truck pull up to a bus stop outside the school. People inside the truck pretended to fire a gun and then "they really started shooting", she told the Chicago Tribune newspaper.
"People were shouting: 'They're shooting,'" Turman said. "It was a lot of people shouting and running."
Police spokeswoman Monique Bond declined to give further details about the victims beyond gender and would not say whether they had attended the basketball game.
She said they were "not necessarily students".
The high school has about 1,600 students and is the alma mater of Oscar-winning actress Jennifer Hudson
