Nigel Farage is to launch a private prosecution against youths involved in a brawl at Manchester Airport which led to protests against “police brutality”.

Britain’s reform leader is expected to announce the move tomorrow to highlight what he sees as a “two-tier justice system” in which right-wing activists are singled out by the courts for harsher treatment.

Outrage erupted in July after partial videos of the incident shared online showed an officer kicking 19-year-old Fahir Muhammed Amas during an attempt to arrest him and his brother Amaad.

Tensions rose further when their lawyer, Akhmed Yakoob, claimed the row was an “attempted assassination”, sparking anti-police protests in the brothers’ hometown of Rochdale.

But dramatic CCTV footage then revealed the three police officers were brutally attacked, leaving one WPC with a broken nose and another officer collapsed on the floor just before the Fahir incident.

Four months later, with the Crown Prosecution Service (CPS) apparently nowhere near announcing charges against the brothers, Mr Farage hired two lawyers to bring them a case.

A source close to Mr Farage said: “It is now November and no charges have been laid – yet those on the right of argument who said nasty things on social media and took to the streets found themselves in jail almost instantly. We have a two-tier justice system in this country.”

The Clacton MP spoke in the summer following riots in English towns and cities following the Southport stabbings that left three girls dead, saying those involved were treated more harshly than other protests.

The storm over the incident in Manchester led to fears the officers involved could be forced into hiding as protests grew – two were suspended over the outcry and are understood to still be.

CCTV footage shows Fahir punching a female police officer in the face, breaking her nose, before knocking down a second female officer as his brother throws.

a “bloody” barrage of punches at an armed male officer, leaving him dazed and collapsed on the floor. Fahir also punched the male officer and grabbed him by the neck in a “choke,” which he only released when a female officer Tasered him.

A well-informed source told The Mail on Sunday that after a “violent altercation” at an airport Starbucks, three officers tried to arrest Fahir while he was using a parking ticket machine; he was shown resistance before Amaad threw a barrage of punches at the male policeman, who crumpled to a row of metal chairs.

Fahir was then shown attacking, first punching one female officer in the head and then smashing the second female officer in the face, knocking her off her feet and leaving her lying on the floor.

Outrage erupted in July after partial videos of the incident shared online showed an officer kicking 19-year-old Fahir Muhammed Amas.

The second female officer suffered a broken nose. The footage also showed Fahir throwing at least four more punches at the first female officer, who was knocked to her knees.

By this time, the male officer had risen to his feet and was pointing his Taser at Amaad. Fahir, however, is shown charging behind the male officer, punching him in the head, then grabbing him by the throat. It is claimed the male officer suffered a suspected broken jaw and may have been temporarily removed.

The fight only ended when the first female officer staggered back to her feet and fired her Taser at Fahir, knocking him down.

At this point, as millions of people have seen on cellphone footage, the male police officer kicks Fahir in the head and appears to beat him as he lies on the floor.

The CPS has the power to prevent a private prosecution by taking it over and ending it – but such a move would be highly controversial in this case.
