SEOUL: A man who opened an emergency exit door during a flight in South Korea was arrested Sunday and faces up to 10 years in prison on a charge of violating the aviation security law, officials said. During a preliminary questioning, the 33-year-old told investigators that he felt suffocated and tried to get off the plane quickly, according to police. Twelve people were slightly injured on Friday after he opened the door of the Asiana Airlines Airbus A321-200, causing air to blast inside the cabin and terrifying passengers. Some testified they suffered severe ear pain and saw others screaming and crying. On Sunday, a district court in Daegu approved a warrant to formally arrest the man.
