New video appears to show the moments before a police officer appears to kick and stomp on the head of a man lying on the ground at Manchester Airport on Tuesday.
The video shows police attempting to detain one man before a fight breaks out as a second man tries to intervene.
An officer was suspended after another video of the same incident was shared online.
The officer is under criminal investigation by the Independent Office for Police Conduct (IOPC) into the alleged assault and has been reprimanded for alleged gross misconduct.
Greater Manchester Police (GMP) said their officers’ actions came after they and other colleagues were “violently attacked” in the Terminal 2 car park at around 8.30pm BST on Tuesday.
The new footage obtained exclusively from Manchester Evening Newsappears to show three officers attempting to detain the man, before another man approaches and tries to intervene.
The BBC has not independently verified the origins of the video.
When the second man intervenes, a fight breaks out and fistfights ensue.
The first man punched two officers, knocking them down, while another officer used a Taser on the second man.
As the first man struggled with the third officer, another officer appeared to fire a Taser, causing both men to fall to the ground.
When the officer got up, the man was lying face down with his arms pinned at his sides.
The elderly woman who fell earlier in the video crawls over to the man who is lying almost motionless.
This is when an officer appears to kick a man in the head as he falls to the ground.
The new footage ends there, but the original video appears to show the officer then stomp on the man’s head.
BBC Verify analysis of five social media videos of the incident suggests the violence did not end there.
Another video appears to show the same officer approaching a different man, stomping on his thigh and striking him in the back of the head with a Taser.
Another officer appeared to fire pepper spray at a passerby who was filming the incident.
The latest videos are not included in the scope of Verify.

Rochdale MP Paul Waugh, who spoke to the family after the incident, said the family of the man who was trampled had appealed for “calmness in all areas”.
he He told BBC Breakfast The family was “painfully aware” that there were “extremists on all sides trying to hijack this incident for their own purposes.”
He said the “strong message” the family wanted to send was that they “have no political agenda.”
A police spokesman said there was a “clear risk” that firearms officers would have their weapons confiscated, and three officers were taken to hospital, one of them with a broken nose.
Four men aged 19, 25, 28 and 31 were arrested following the incident on suspicion of disorder and assault and later released on bail.
Police said they understood the “deep concerns” that had been “widely raised” about the footage.
Mayor of Greater Manchester, Andy Burnham, said the incident was a “complex situation with two sides” and urged the public not to jump to judgment.
“It’s unfortunate that we couldn’t release more video, but this is because the investigation is ongoing,” he said.
“The public must now take a step back and wait for the IOPC’s criminal investigation into officers’ conduct, and GMP’s investigation into other potential offences, to progress so that the full picture can emerge.”
Human rights lawyer Amar Anwar said: BBC News Night He was disappointed that leading politicians, including Mr Burnham, had called on the public to consider the context of the incident.
He said there was “no justification” for officers to act in this way, adding that the circumstances were “irrelevant.”
