"his actions were wholly inappropriate for a serving police officer.”
Adnan Ali, aged 36, of Manchester, was jailed for five years after he sexually assaulted police cadets.
Ali carried out the abuse between 2015 and 2018 on Greater Manchester Police’s (GMP) volunteer cadet scheme.
He was arrested and suspended in 2018 following a complaint that he had been behaving inappropriately towards a 16-year-old boy.
Electronic devices revealed thousands of messages, identifying further victims.
His DNA was also found in bodily fluids on a police office carpet.
Chief Constable Stephen Watson said: “PC Ali engaged in sexual activity on police premises in an area that was periodically used by young apprentices and Cadets.
“This was a fundamental breach of the public’s trust in police officers and inevitably brings the profession into disrepute.
“Further, in doing so, PC Ali must have been aware that his actions were wholly inappropriate for a serving police officer.”
He was sacked after being found guilty of gross misconduct in April 2022.
In April 2023, Ali was found guilty of sexual assault and 15 counts of misconduct in a public office.
He was jailed for five years and GMP are now seeking to remove his pension.
Head of GMP’s Professional Standards Branch, Chief Superintendent Mike Allen said:
“At a time when policing is subject to such intense scrutiny, particularly in relation to sexual misconduct and abuse of position, Ali’s behaviour will, understandably, damage trust and confidence in the force.
“However, the public should be reassured by the action GMP, the IOPC and the CPS have taken to secure his arrest, suspension, prosecution and dismissal.
“Though Ali is now in prison thanks to the commendable bravery of the victims and integrity of those who worked with him, it is the view of Greater Manchester Police that he should never reap the benefits of having been an officer.
“He has already been added to the College of Policing’s barred list – preventing him from serving for the rest of his life, and we are now following the process to try to ensure that he loses his valuable pension.”
Senior officers have admitted more could have been done to supervise Ali but that action is ongoing to “ensure predatory employees are rooted and booted out”.
The Independent Office for Police Conduct said the case had shown “serious failings” in the way GMP cadet schemes were managed.
However, it said it welcomed “a range of steps taken” to improve the supervision of officers working on the courses.
