An American Airlines flight headed to New York City from Miami was forced to divert to Jacksonville, Florida, after someone sprayed pepper spray.

A spokesperson for the Federal Aviation Administration told FOX Business that the incident happened Sunday on American Airlines Flight 1680 from Miami to New York City.

The spokesperson said the flight needed to be diverted to Jacksonville International Airport in Florida after someone inadvertently sprayed a bottle of pepper spray on the plane.

The aircraft was cleaned after the diversion and continued to New York City's LaGuardia Airport.

The FAA will investigate the incident.

FOX Business reached out to American Airlines for comment.

Pepper spray is a banned substance to possess as a carry-on item inside planes, according to the Transportation Security Administration. However, a 4 fl. oz. container of mace or pepper spray is allowed in checked baggage — as long as there's a safety mechanism attached to prevent discharge, the TSA said.
