Update from KSTP.com
Here's the latest:
Areas of Minneapolis-St. Paul International Airport were evacuated Tuesday afternoon when a bomb-sniffing dog reacted to a piece of luggage.
Around 2 p.m., the dog indicated the possible presence of explosive material in a bag coming off one of the baggage carousels on the baggage claim level.
Officials cleared people from portions of baggage claim and the upper and lower roadways used to drop-off and pick-up passengers.
As of 3 p.m., the east end of the ticketing level of the Lindbergh Terminal was also shut down along with four security checkpoints.
A 5 EYEWITNESS NEWS crew estimated that there were about 600 people in line waiting to get through the remaining checkpoints.
The east end of the terminal includes the ticketing counters for United and American Airlines.
One federal official told 5 EYEWITNESS NEWS that the bag that ellicited the response from the dog might have been the package marked "last bag." Airlines place such bags on carousels to let passengers know that all bags have been unloaded from a flight.
Police are trying to determine if the bag came into contact with other bags or items that might have contained a dangerous substance.
