Dr Alan Billings, South Yorkshire Police and Crime Commissioner, said: “At the weekend there was a demonstration in Sheffield City Centre organised by the South Yorkshire Migration and Asylum Action Group (SYMAAG) to show solidarity with Kurdish people in Iraq following interventions there by Turkish armed forces.

“About forty people were present and the policing was at first minimal. However, at some point the police intervened and an arrest was made.

“I have had a number of people contact me to protest about the policing from this point onwards.

“As a result, I met the Deputy Chief Constable this morning and he has agreed to review the police response.

“Over the next few days CCTV will be collected from around the area and the whole incident examined.

“I urge those who are expressing strong views – especially those who were not themselves present – to await the outcome of the review.”
