ACTIVISTS have demanded action on racist police violence after a Muslim man was left hospitalised in a brutal attack by a Greater Manchester officer.

Chants of “No justice, no peace, no racist police” echoed outside Greater Manchester Mayor Andy Burnham’s office on Thursday evening.

Hundreds joined the Stand Up to Racism protest after Mohammad Fahir, 19, and his brother Amaad were kicked and attacked by a GMP officer at Manchester airport on Wednesday. 

A cop was seen stamping on Mr Fahir’s head while surrounded by a gang of other officers in footage that has been circulated on social media.

His family say they are “traumatised” after the incident, and Mohammad has been found to have a cyst in his brain, his lawyer said.

Protesters held signs saying “serve and protect means GMP will stamp on our heads” and “GMP is racist.”

One of the demonstrators, Shah Rahman, from Oldham, said communities were “very scared when police have no limits.”

The officer seen attacking the brothers has been suspended, but campaigners argue he should be sacked immediately. 

The Independent Office for Police Conduct has promised a “thorough and robust” investigation following the footage’s release.

After reviewing the video, Mr Burnham told BBC Radio Manchester the incident showed a “fast-moving and complicated” situation and claimed there were “issues for both sides.”

Former Met chief superintendent Dal Babu told BBC Radio 4 that the force used was “totally excessive” and that he believes “racism played a significant part in this.”

Other footage has emerged showing a man who appears to be a bystander being pepper-sprayed by police while filming the incident. 

The family’s lawyer Akhmed Yakoob said Mr Fahir’s mother had suffered a black eye after being struck by a cop.

Speaking to LBC this morning, Mr Yakoob said she had been subjected to racial abuse during an earlier exchange on an aeroplane.

GMP said they were called to Terminal 2 following reports of a fight.

They say that three officers were attacked. Four men were arrested on suspicion of affray and assaulting emergency service workers

Home Secretary Yvette Cooper said it was “extremely important” that the investigation happen “swiftly” and “thoroughly.”
