TWO foreigners were offloaded from a Manila-bound Cebu Pacific (CEB) plane after they engaged in fisticuffs on Monday night, Police Aviation Security Group (Avsegroup) said. American national Robert William Dismus, 65, and 35-year-old Chinese Fan Wah John Kung were aboard the CEB flight 5J788 and standing on the cabin aisle waiting to take a seat when Dismus inadvertently shoved Fan from behind, Butuan Airport Avsegroup head Insp. Alexis Avenido said. Fan reacted and engaged the Dismus to a fistfight that threw the plane into confusion. They were later released and bought new tickets for the next available flight to Manila.
