Two men were removed from Wednesday's flight ZB 613 that was due to arrive at Heathrow airport from Malaga, the reason being they were acting suspiciously and speaking Arabic. Spanish officers boarded the plane and removed the men after 20 minutes.
The incident started when some passengers refused to board the plane.
"They went to the front of the queue, went to the back of the queue, and then they went and sat down by themselves" said one of the passengers.
The remaining passengers were removed as the luggage was swept for explosives. David Reynolds, of the British Airline Pilots Association said "Clearly, we can't have a situation where one passenger decides that another passenger isn't going to fly."
