A police officer has been suspended after footage shared on social media showed a suspect being kicked in the head and stamped on at Manchester Airport.
The suspect has been named as Fahir in an Instagram video where he appears alongside his lawyer Akhmed Yakoob.
The lawyer is also representing a second man who was arrested in the incident at Manchester Airport and names him as Amaad.
Mr Yakoob, who is the only one who speaks in the video, does not confirm whether Fahir and Amaad are brothers but says they will be making a formal complaint accusing Rochdale Police of assaulting them and "their elderly mother".
Greater Manchester Police (GMP) had been responding to reports of an assault at Terminal 2 at 8.25pm on Tuesday before the footage of the police officer stamping on Fahir was filmed.
The force has said three officers were injured in a subsequent altercation and there was a "clear risk" of firearms being snatched from officers who were carrying weapons.
