John F Kennedy International Airport's Terminal 8 was evacuated last night after reports of shots being fired - but all was not as it seemed.
After the area had been cleared following reports of "clapping and banging", the NYPD's Special Ops team tweeted: "All terminals searched & cleared.
"Negative results. All affected terminals will resume operations shortly.
"No shots were fired."
And now it appears we may know the reason for the initial panic.
Authorities say reports of the shooting emerged at "around 9.30pm" US time - the same time that Usain Bolt won his 100m race and took home an incredible third-straight gold medal.
One passenger wrote on Twitter: "I've been stranded in JFK for 6 hours due to this. Thanks Usain."
"Usain Bolt is so incredible he caused an evacuation at JFK tonight," said another user.
