A PASSENGER already on board a plane at the Davao International Airport was arrested Sunday for making a bomb joke, an act punishable by imprisonment. The Civil Aviation Authority of the Philippines (CAAP) identified the passenger as Ramon Barrios, who was booked on PAL Express flight GAP2364 bound for Cebu. The flight was delayed as all passengers, following protocol, were temporarily offloaded while an aircraft security check was conducted. Airport Officer-in-Charge Rex A. Obcena reported that Mr. Barrios, who said his reference to a bomb was only a joke, was consequently arrested by the Police Aviation Security Unit and has been turned over to the Davao City police for the filing of appropriate charges. Under Presidential Decree 1727, or the Anti-Bomb Joke Law, violators may face imprisonment of not more than five years or a fine of not more than P40,000, or both, at the discretion of the court.
