Three separate shootings left 10 people wounded and scattered hundreds in downtown Indianapolis during the crowded Indiana

Black Expo, police said early Sunday.

Police spokesman Lt. Jeff Duhamell said authorities made no immediate arrests directly tied to the shootings and investigators

were seeking leads to the suspects.

None of the victims' injuries were life-threatening, Duhamell told The Associated Press, adding police had made three

unrelated arrests on weapons charges.

The shooting began when several shots rang out around 9:30 p.m. Saturday near Circle Centre mall, leaving eight people wounded

and sending people running, Duhamell said.

He said a second shooting occurred nearby just minutes after the initial shooting and left one young man wounded. He added

that the third shooting occurred around 11:30 p.m. and left another man wounded.

Duhamell said the shooting victims were all males between 10 and 18 years old. He said most were taken to two area hospitals

where they were in good condition early Sunday. One person was treated at the scene.

Authorities say none of the shootings occurred at venues playing host to Black Expo activities, but police patrolling amid

the crowd moving about the downtown area quickly converged on the scene.

"It's pretty unusual to have this many shots in one time. It's very unfortunate," Duhamell said.

Duhamell said investigators had no immediate report on a possible motive but were trying to determine if any of the shootings

were gang-related.

He said hundreds of officers had been assigned to policing the 10-day event, which concludes later Sunday.
