<p>German air traffic control warned the crew of the Dublin-Krakow flight of the potential threat on Sunday, Ryanair said in a statement, without elaborating. It said the captain followed procedures and diverted to Berlin, the nearest airport.</p>
<p>Passengers were taken off the plane “to facilitate extensive security checks of passengers and all baggage,” the airline said. Once they were cleared, passengers were flown to Krakow on a spare plane after a seven-hour delay. </p>
<p>German federal police said early Monday morning that their deployment was finished, but declined to give details of what led to it, news agency dpa reported. A search of the plane found nothing untoward.</p>
