A gunman has opened fire in a downtown Cleveland high school and five people have been taken to an area hospital.

Mayor Frank Jackson said three young people and two adults have received injuries, that the school,SuccessTech Academy had been secured and there was only one suspect.

Ronnell Jackson, 15, said he saw the shooter running down a school hallway.

“He was about to shoot me but I got out just in time,” he said.

Another student, Doneisha LeVert, said she heard the principal say “Code Blue” over the public address system, and the students started running. She said she hid in a closet with some of her friends.

Students stood outside the building, many in tears and on cell phones. Family members also stood outside, anxiously waiting for their children to be released.

The small, alternative high school is in the center of downtown across from the FBI’s offices and three blocks from where the Cleveland Browns play football. The school enrolls 240 students grades nine through 12 and emphasizes technology education. All the students are poor under federal poverty guidelines.
