A passenger aboard a United Airlines flight from Hong Kong to Newark allegedly became disruptive on Monday, apparently claiming fellow travelers had been poisoned, officials said.
Flight 116 continued as scheduled and landed safely around 1:40 p.m. ET, according to online tracking service flightaware.com.
A law enforcement official said authorities were investigating a claim that passengers aboard the Boeing 777 had been poisoned, but it was not clear if that was true.
No other details were immediately available.
The source confirmed that the FBI was handling the incident and taking it seriously.
The airline said a passenger became disruptive, but that the crew followed procedures and got the situation under control.
