Two aircraft were forced to make emergency landings within hours of each other on Tuesday at Owen Roberts International Airport, Grand Cayman.
Both aircraft landed safely.
One of the incidents involved an American Airlines B737 aircraft.
American Airlines flight 941 was en route from San Pedro, Honduras to Miami, but was diverted to Owen Roberts having declared a full emergency, said CEO of the Cayman Islands Airports Authority David Frederick.
The emergency resulted from an unruly passenger who reportedly attacked another passenger.
All emergency services were notified and responded according to plans, said Mr. Frederick.
The alleged offender on the American Airlines flight was taken into police custody and the RCIPS has begun an investigation of the incident.
One passenger was reportedly injured and treated at the scene.
Mr. Frederick said that whether a landing fee is charged depends on the circumstances of such a situation.
He would not answer additional questions on whether the fee would be waived in this instance.
American Airlines had not responded to questions on the incident by press time.
A two-engine private plane also landed safely Tuesday morning at Owen Roberts International Airport after reporting a possible fire in one of its engines.
Two people on board the plane were uninjured when it landed just before noon. Upon inspection of the craft, no fire was ever located.
As in all aircraft emergencies in Cayman, the fire service was placed on standby at the runway until the plane touched down.
The all-clear was given shortly after the craft landed.
