A passenger has been taken into custody after security screeners detected something suspicious in a checked bag at Miami International Airport, U.S. federal officials said Friday. A statement by the Transportation Security Administration said its investigators, a Miami-Dade police bomb squad and other law-enforcement agencies were on the scene. Four of the six Miami airport terminals had been evacuated and airport roadways also were closed as a safety precaution, the statement said, without providing further details about the item which was found about 9 p.m. local time Thursday. Authorities said the evacuation continued early Friday and urged anyone with departures from Miami to check with their carrier.
