Police officer who sexually assaulted a child while on duty sacked
'He has no right to be in police uniform'

A ‘morally reprehensible’ police officer who sexually assaulted a child while on duty has been sacked and barred from service.
GMP held an accelerated misconduct hearing with PC Dean Dempster, 35, and he has been dismissed without notice.
The disgraced officer admitted ‘sexually touching’ the six-year-old child in December 2023 and is set to be sentenced at a later date.
He was a response officer in Oldham at the time that the offence was reported, and was arrested by a supervisor when he returned to work the next day.
A senior officer has now said that Dempster ‘has no right to be in police uniform or in a position to serve the public’.
Another said it was ‘among the most distressing cases ever presented’ and a ‘despicable betrayal’ of police duties.
Dempster was convicted of sexually assaulting a young girl while responding to an incident on 29 December 2023.
He was convicted at Liverpool Crown Court in February and remained suspended since being charged at the end of last year.
Presiding over today’s hearing, CC Watson found PC Dempster’s conduct amounted to gross misconduct, saying: “This sexual assault occurred whilst the officer was on duty and where the victim was totally trusting and reliant on him performing his duties professionally, compassionately and with her welfare uppermost in his thoughts.
“It is this most egregious breach of trust of an innocent young child that is most upsetting aspect of this case and something that clearly amounts to an aggravating factor.
“I consider this case to be among the most distressing ever presented to me such is the despicable betrayal of all that is inherent in being a decent police officer.
“I have no hesitation whatsoever in dismissing PC Dempster from the service with immediate effect.”
Detective Chief Superintendent Mike Allen, head of GMP’s Professional Standards Directorate, said: “Dean Dempster is not a police officer, he’s a child sex offender who has no right to be in police uniform or in a position to serve the public.
“We have no time for people like Dempster who should not be in GMP and does not represent us.
“This is why we’re increasingly using accelerated misconduct hearings to root out and boot out officers who are unfit to serve in our uniform, and this work will continue while ever they remain.”
Dempster has been added to the College of Policing Barred List by Chief Constable Stephen Watson, who described Dempster’s actions as ‘morally reprehensible’.
GMP used accelerated proceedings as part of its pledge to ‘root and boot’ officers unfit to serve the public.
The force is now writing to the Deputy Mayor of GM to appeal for Dempster to lose his right to a police pension.
