Twitter user @ldtnubs tweeted: “All of Terminal Three being evacuated at Manchester Airport. There is no news yet, but everyone is leaving.” David Williams, who tweets with the handle @david4lcs, said: “Manchester Airport evacuation from Terminal 3. Chaotic. “Everyone said to leave and get out, but almost no one was listening to instructions. Now open again. Long queues.” The tweet was posted with a video showing travelers queuing inside the terminal while the alarm was still sounding, advising people to listen for further instructions from staff. Greater Manchester Police told Express.co.uk they have not received any reports from the airport indicating problems. A Manchester Airport spokesman confirmed the incident was a false alarm as a result of a small area being evacuated due to one of the red boxes being detonated, with the situation now normal. The latest incident comes amid growing frustration at UK airports, with passengers complaining of long complaining queues leading out of airport terminals that have forced many to miss flights and lose hundreds of pounds. Airline passengers have been hit by disruption for several months, with the situation exacerbated by a surge in demand sparked by the school half-term holidays and the four-day Platinum Jubilee weekend.
