Around 10:30 p.m. on Friday, Wiz Khalifa's concert at Noblesville's Ruoff Music Center unexpectedly stopped as attendees started to leave.

From the audience area close to the front and left side of the stage, no gunfire were heard or observed. The majority of guests left through the main door, while some had to climb over closed gates or wire fences.

As soon as the music stopped, Khalifa and his band left the stage.

Some audience members were making cell phone calls in the Ruoff's staff parking lot. Others sobbed and hugged one another. Some people ran away and hid in the nearby fields.

There were police cars and an ambulance in the back parking lots.

Logic and fellow rapper Khalifa were co-headlining the Vinyl Verse tour, and Khalifa was around 45 minutes into his performance. The night's final set was his. Earlier in the evening, Fedd the Lord and 24kGoldn gave performances.
