Detroit ? Gunmen in a green minivan opened fire on a group of teenagers waiting at a bus stop near a Detroit school on Tuesday, wounding seven including two who were in critical condition, authorities said.

Five of the teens had just left Cody Ninth Grade Academy, where they were taking summer classes, when they were shot at the nearby bus stop.

The gunmen exited a vehicle and “asked for a person by name” before they “opened fire at the crowd,” said Detroit Public Schools Police Chief Roderick Grimes.

Detroit Police were looking for two suspects in a green minivan, said spokesman Rod Liggons. Officers were interviewing some of the victims in the hospital Tuesday evening, he said.

Four boys and three girls ranging in age from 14 to 17 years old were hospitalized, two of them — a 16-year-old boy and a 17-year-old female — in critical condition, said Deputy Chief James Tolbert.
