Police evacuated John F. Kennedy Airport’s Terminal 8 Sunday night after they received reports that shots had been fired. After a preliminary investigation, cops now say there was no shooting—with one official saying “clapping and banging” by people watching the Olympics may have been misinterpreted as gunfire.

The Port Authority told NBC the initial call came in “around 9:30"—or roughly one minute after Usain Bolt finished winning his third-straight gold medal in the 100 meters. The reports of a shooting spread like wildfire on Twitter, with authorities hesitant to confirm anything; they evacuating the terminal for precautionary reasons, while the FAA placed a brief ground stop at the airport.
