Captain Ryan Pedigo said that five people with injuries from gunfire had been transported to a local hospital.

“Officers immediately converged on the area and located multiple wounded individuals,” Pedigo said in an emailed statement. “It is not currently known how many of the wounded individuals suffered direct gunshot wounds or if their injuries were a result of being struck by bullet fragments.”

Pedigo said that police transported one person to the hospital in a squad car, while two others were taken by private vehicle.

Ambulances also transported two people, one from the scene and another from a gas station who had “injuries believed to be related to the shooting.”

Pedigo said no one was in custody as of Sunday morning. He asked that individuals with information or video of the shooting to contact police.

The Monroe Co. Sheriff’s Office and Indiana State Police assisted at the scene, and investigators used drones and a helicopter, he said.

Video uploaded to social media showed people fleeing through the street.

IU sent alerts to students and staff soon after the incident urging them to take shelter, lock their doors, and stay away from Kirkwood Avenue.

The messages said that no shots were fired on campus.

Kirkwood Avenue is a central area for late-night events surrounding the Little 500 bicycle race that draws tens of thousands to Bloomington each year.
