Police in Miami report that fifteen people have been injured in a shooting at a Miami nightclub early Sunday morning. The injured ranged in age from 11 to 25 and at least one person is in critical condition, the AP reports.

According to the Associated Press, when police arrived to a nightclub called The Spot at around 1 a.m. on Sunday morning, the venue was in chaos:

Rescuers found wounded people inside and outside the club, some too hurt to flee, Miami Fire Rescue Capt. Ignatius Carroll said.

He told The Associated Press that the first emergency crews arriving on the scene were warned to use caution "because there was still active shooting taking place in the area."

Investigators are still unclear on what spurred the shooting and are in the process of going from hospital to hospital to interview witnesses. Police still don't know why children as young as eleven were permitted at the nightclub at such a late hour, but are hoping to learn more through their investigation.
