A rap concert at SOBs in New York City was shut down after a gunman opened fire inside the venue last night (Sept. 11).

According to the NY Daily News, Washington D.C.-area rapper Fat Trel was celebrating the release of his 'SDMG' mixtape at SOBs when police got a call at 12:15AM about shots fired during the concert. Four people were shot and two had to be transported to Beth Israel Medical Center. The other two suffered graze wounds from bullets.

The scene was described by many who were present as chaotic, which is what fellow attendee DJ Zeke can attest to. “I’ve never been so scared because I didn’t know where the shots were coming from,” he tells the NY Daily News. “Everybody is jumping on each other, trying to get away from the action.” He said about nine shots were fired.
