Police have passed a file to the Crown Prosecution Service on whether to press charges over last month’s Manchester Airport incident which left three officers injured.

A member of the public had his head stamped on in clashes which have already prompted an investigation by the Independent Office for Police Conduct.

The force launched an investigation after video footage emerged of violent scenes at the airport on July 23.

The first clip, which went viral on social media, appeared to show a police officer kicking and stamping on the head of Fahir Amaaz, 19, while he was on the ground.

A second video then showed an altercation which broke out in the moments before the incident.

Videos emerged showing clashes breaking out between members of the public and Greater Manchester Police officers at Manchester Airport on July 23

Mr Amaaz and his brother Muhammad Amaad, 25, appeared to throw punches at a male police officer – while two female officers were also hit to the ground before Mr Amaaz was Tasered.

Two police officers remain under criminal investigation for assault in relation to the incident, according to the IOPC.

And now Greater Manchester Police has said in a statement this morning: ‘We have submitted a file to CPS for advice as part of our investigation into incidents at Manchester Airport on 23rd July.

‘We have submitted a comprehensive file of evidence to the Crown Prosecution Service for advice as part of an investigation into a series of alleged criminal offences which saw three police officers injured at Manchester Airport in July.

‘GMP Major Incident Team investigators, led by a highly experienced Senior Investigating Officer, have been thoroughly investigating the incident.

‘Four men remain on police bail.

‘A separate and independent investigation into our officers’ actions, by the Independent Office for Police Conduct, remains ongoing.’

Protests broke out in Manchester and Rochdale after the first video emerged.

In a press conference earlier this month, the lawyer of the family involved in the incident said the men’s mother, 56-year-old Shameem Akhtar, was hit in the face with a Taser by an officer.

In the days after the incident, the IOPC said a GMP constable was under criminal investigation for assault in connection with the arrests of the brothers.

The watchdog then revealed a second officer had been advised they were also under criminal investigation for assault, relating to an incident shortly afterwards when two other men were arrested.

The officer is also being investigated for potential gross misconduct for alleged breaches of police professional standards including their use of force.

An IOPC spokesman said it had received a further referral from GMP of a complaint, detailing several allegations, from one of the people involved.

Catherine Bates, IOPC regional director, said: ‘It is clear the situation at Manchester Airport was complex and escalated rapidly.

‘The incident, which resulted in injuries to police officers and members of the public, has caused understandable concern and we are working hard to piece together all of the relevant events on that day.

‘In parallel, Greater Manchester Police is investigating whether any criminal offences were committed by members of the public during the initial altercation and the subsequent arrests.

‘These investigations are separate, and we are liaising with the Crown Prosecution Service to establish how they can progress in parallel.’
