A 70-year-old American scientist is being questioned after screeners spotted a metal canister in his luggage that looked like a pipe bomb around 9pm last night, triggering a shutdown of Miami International Airport. Four of six terminals and airport roadways were closed until 4am, AP reports.
"He's being very cooperative," said an FBI agent, who added that the unnamed man was on a flight that flew into Miami, though he would not say from where. "He's not under arrest at this time. We don't know if a crime has been committed here." The item found in the man's luggage has been brought to a lab for more testing.
