A GMP officer has received a written warning for his use of CS Spray during the arrest of a 13-year-old.
The written warning was issued by following an investigation by the Independent Office for Police Conduct (IOPC).
The watchdog concluded that "the force used by the officer in this case was neither reasonable nor proportionate and could have been avoided."
The IOPC investigation lasted five months and followed the referral by the force of a complaint from the child’s father in August 2020.
The officer faced a misconduct meeting this week, where he was found to have breached the standards of professional behaviour in relation to his use of force.
In a statement the IOPC said: "Our investigation found that two officers in an unmarked police vehicle in the Moss Side area of Manchester reported seeing the boy in a park involved in what they suspected was an exchange of drugs. After seeing the officers, the boy ran off.
"After officers caught up with the boy and made two failed attempts to stop and search him, one of the officers ran after him and used CS spray in the child’s face as he turned his head to look back while continuing to run away.
"During our investigation, which concluded in December 2020, we obtained witness statements, conducted interviews, viewed body worn video footage and analysed GMP’s policies and procedures.
"We found the officer had a case to answer for misconduct and the force arranged disciplinary proceedings."
IOPC Regional Director Amanda Rowe said: “We found the force used by the officer in this case was neither reasonable nor proportionate and could have been avoided.
“We found no evidence the boy posed any immediate threat to police or the public and the officer’s conduct during the incident fell short of what would be expected of a serving officer.
“While no serious injury was caused to the child, we know interactions like this with police can have a lasting and damaging impact on public confidence in the police. Police officers are trained to deal with challenging situations and should only deploy CS Spray when it is necessary, proportionate and reasonable.”
In a statement GMP said: "In this case, the officer was given a written warning following a voluntarily referral from our Professional Standards Branch to the IOPC.
"We remain committed to addressing any misconduct of any kind, at any rank, and will take swift and robust action to ensure we maintain the confidence of the public we serve."
