Seven minors were hospitalized with injuries late Saturday night after a mass shooting broke out in downtown Indianapolis, police said.

The children and teenagers, who were between the ages of 12 and 17 years old, each sustained gunshot wounds in the shooting, which happened just after 11 p.m. local time outside of the city’s Circle Centre Mall. CBS affiliate WTTV shared images from the scene.

No suspects have been arrested, but investigators believe more than one weapon was used to carry out the shooting, according to the Indianapolis Metro Police Department. A police report filed after the incident identified four boys and three girls as victims, all of whom were stable when Indianapolis Deputy Police Chief Tanya Terry gave preliminary details about the incident at a briefing early Sunday morning.
