SAN ANTONIO -- A passenger who was detained after flight attendants said he tampered with a bathroom smoke detector was determined to be "not suspicious at all," the FBI said Sunday.
The passenger, a San Antonio man whose identity wasn't released, was questioned Saturday after flight attendants reported suspicious activity. Explosives experts swept the Delta Air Lines plane after it arrived from Atlanta but found nothing.
