Britain’s highest-ranking female police officer is hit with ANOTHER bullying claim

Britain’s highest-ranking female police officer faces fresh bullying allegations amid claims she deliberately isolated a police dog charity.

The Met’s Deputy Commissioner Pippa Mills was also accused of breaching professional standards of honesty and integrity and discreditable conduct.

A source close to the investigation told the Daily Mail that the allegations were made by The Thin Blue Paw Foundation, a national charity supporting serving and retired police dogs in the UK.

The organization is understood to have accused AC Mills, 51, of the National Police Chiefs’ Council’s police dogs, of consistently refusing to engage with them.

They claimed he unduly favored other charities, such as the National Trust for Retired Service Animals (NFRSA), because of his ‘personal friendships’ with the people who run them.

AC Mills denied the allegations and the complaint was initially disconfirmed by the Metropolitan Police.

But a review by the Independent Office for Police Conduct has since found Thin Blue Claw’s concerns were not fully addressed by police.

The watchdog ordered further investigations into allegations that AC Mills had repeatedly ignored the charity; He said bosses perceived this as bullying and that it was a “serious allegation”.

It comes just weeks after it was revealed that AC Mills was also being investigated for bullying an officer under his command at the Metropolitan Police.

It is understood he was accused of bullying behaviour, with the investigation focusing on breaches of ‘authority, respect and courtesy’.

Speaking about the latest allegations, an insider said the Thin Blue Paw Foundation believes they are being ‘bullied over lockdown’ by AC Mills.

They argued that their alleged refusal to participate in the charity led to their exclusion from events and preference being given to other organisations.

Evidence submitted to the Met Police’s complaints department included photographs of the senior constable interacting with other police dog charities.

These include being at Crufts in 2024 and undertaking a 1,022-mile charity bike ride on a police motorbike in 2023 to raise money for NFRSA.

The Thin Blue Paw Foundation first made a formal complaint to the Metropolitan Police’s Professional Standards Department about AC Mills’ conduct.

However, this was rejected in August and referred to the Independent Office for Police Conduct for review; The charity claimed its concerns were not properly addressed.

In response to the allegations, AC Mills denied using his position to ‘unduly influence’ support for different police dog charities.

He said he never tried to dissuade police forces and organizations from working with the Thin Blue Claw Foundation.

The Thin Blue Paw Foundation is a national charity supporting retired police dogs serving across the UK.

Chief Constables can personally choose which charities they work with.

A spokesperson for The Thin Blue Paw confirmed to the Daily Mail that a complaint had been made.

They said: ‘The Thin Blue Claw Foundation can confirm that it has made a formal complaint regarding the on- and off-duty conduct of a senior police officer in the Metropolitan Police.

‘Due to concerns not being addressed proportionately or adequately by the Metropolitan Police Professional Standards Department, the matter was subsequently referred to the Independent Office for Police Conduct (IOPC) for further investigation.

‘These concerns relate to the officer’s conduct within the scope of his portfolio role at the National Police Chiefs’ Council (NPCC).

‘We cannot comment further while these matters are being reviewed by the IOPC.’

An IOPC spokesperson said: ‘On 10 September 2025 we received a request to review the handling of a complaint by the Met Police.

‘The complaint concerns a senior Met Police officer and allegations of bullying and breaches of professional standards, including honesty, integrity and discreditable conduct.

‘The review will be allocated to a casework manager who will consider whether the outcome or handling of the complaint was reasonable and proportionate and whether any further action is required.

‘Our role when carrying out a review is to decide whether the force’s handling of the complaint or its outcome was reasonable and proportionate.

‘We cannot investigate the complaint.’

The Metropolitan Police refused to comment on the allegations when contacted by the Daily Mail.

Richard Jackson (pictured) appeared at Worcester Magistrates’ Court in June accused of stalking AC Mills.

AC Mills joined the Metropolitan Police two years ago. He was hired by commissioner Sir Mark Rowley to rebuild trust in the force following the murder of Sarah Everard by firearms officer Wayne Couzens in 2021.

Earlier this year, she revealed she had sleepless nights after being followed by an 80-year-old man.

His pursuer, Richard Jackson, appeared at Worcester Magistrates’ Court in June.

The Deputy Commissioner told the court the pensioner first targeted him between 2021 and 2023 when he was Chief Constable of West Mercia Police.

The court heard Jackson also wandered around outside New Scotland Yard when he moved into his current role.

During this time, Jackson bombarded her with emails and messages.

Prosecutor Colin Le Roux said: ‘He had no reason to email Ms Mills.’

‘Attended New Scotland Yard twice.’

The court heard Jackson was angry with West Mercia Police over an incident that occurred in 2004, before Ms Mills joined the force.

In a victim impact statement read out in court, Ms Mills said: ‘This is literally giving me sleepless nights.

‘I’m afraid to go from the station to New Scotland Yard and come back in the evening. I am extremely careful.

‘This has had a huge impact on my lifestyle, including me not feeling safe in my home if she finds out where I live.

‘If the doorbell rings, I jump.’

A Met Police spokesman previously said of allegations of oppressive behavior against AC Mills: ‘We can confirm that the Met’s Directorate of Professional Standards (DPS) is carrying out an investigation following allegations of misconduct by a senior officer.

‘The officer was served with a notice of investigation regarding alleged breaches of the police’s standards of professional conduct in relation to ‘Authority, Respect and Courtesy’ and ‘Discreditable Conduct’.

‘The allegations relate specifically to their behavior towards a colleague or colleagues.

‘The notification of investigation does not imply any indication of guilt and the investigation is at an early stage.

‘The Met expects all officers to comply with the highest standards of conduct; ‘We take the allegations extremely seriously and treat all parties fairly.’
