Did Usain Bolt’s Olympic dash trigger JFK airport scare?

That’s one of the possibilities police were exploring Monday as they reviewed security camera footage and interviewed witnesses about the chain-reaction scare that rippled through two airport terminals Sunday night in the minutes after Usain Bolt sprinted to a gold medal victory in the 100-meter dash. 

An internal New York Police Department briefing document, obtained by The Associated Press, said a preliminary video review showed that some travelers had started to act “extremely disruptive’’ while watching the Olympics on televisions in Terminal 8. That set off a chain reaction, with other people running away from the commotion, the document said. 

Then, at 9:34 pm, about seven minutes after Bolt’s run, police received an anonymous 911 call from a woman reporting gunshots in the terminal. 

It isn’t clear how the celebration might have come to be misinterpreted a few minutes later as gunshots. 

Investigators were also unsure exactly how the commotion spread across the airport campus to Terminal 1, where rumors about a shooter, combined with the sound of alarms and sight of armed police, convinced some people that an attack was underway.
