This is the shocking moment a British man battled several German police officers following a confrontation with airport security.

The man, 38, can be seen near a Lufthansa check-in gate at Frankfurt Airport in a brawl with officers, single-handedly knocking at least three of them to the ground.

The confrontation began after a woman believed to be travelling with him fell over at security. It is thought that the man lashed out after complaining about flights.

In the footage, the man shoves an officer to the floor, turning to fight off two others with punches and kicks.

More than four officers can be seen struggling to control the man during the confrontation. They were jeered and whistled by a crowd of onlookers.

The man can also be heard shouting "I am a British citizen!" before beginning his rampage.

The tussle ends only when the man suddenly collapses to the floor as two women -- thought to be known to the man -- approach him.

Spiegel Online said a Taser had not been used but it is unclear what stopped the assault.

A police spokesman told the site: "The attacker was an Englishman who was worried about his wife. She had circulatory problems."

Bad weather meant that around 7,000 passengers had their flights cancelled and were kept overnight in Frankfurt on Friday July 23, when the altercation is believed to have taken place.

The mood of the travellers was described by an airport spokesman as "certainly not the best".

Frankfurt Police denied the incident was related to terrorism.

In a post on Facebook, they said the video was being used to spread false messages and terror.

It goes on to explain the situation where thousands of passengers were stranded at the airport. The man threatened an airport employee and subjected them to verbal abuse, they added.

The police intervened without success, leading to the fight in which the man and officers were "slightly injured".

Frankfurt Police stressed that the man had no terrorist background and it was not an attack.
