(CNN) -- Authorities say a passenger aboard a United Airlines flight from Hong Kong to Newark allegedly became disruptive on Monday, apparently claiming fellow travelers had been poisoned.
Flight 116 continued as scheduled and is expected to land shortly, the airline said in a statement.
It was not known if the claim about poisoned passengers was true. No other details were available.
A law enforcement source confirmed that the FBI was handling the incident and taking it seriously.
The airline said the passenger became disruptive, but that the crew followed procedures and the situation was under control as the jetliner approached Newark.
