Britain's highest-ranking female police officer is being investigated for bullying allegations, it has been reported.
The Met's assistant commissioner Pippa Mills is understood to have been accused of overbearing conduct by an officer working under her at the force.
An internal investigation into alleged breaches of 'authority, respect and courtesy' as well as 'discreditable conduct' has been launched, according to The Sun.
A source told the publication: 'The Met are dealing with this one with the utmost seriousness.'
'It is vital for the integrity of the organisation that this inquiry is dealt with robustly and thoroughly.'
Ms Mills, 51, who revealed earlier this year she was having sleepless nights after being stalked by an 80-year-old man, joined the Met two years ago.
She was recruited by commissioner Sir Mark Rowley to rebuild trust in the force following the murder of Sarah Everard by Wayne Couzens, a serving firearms officer, in 2021.
It is understood that Ms Mills has been moved temporarily to a non-operational role until the probe into her conduct is complete.
This is not the first time Ms Mills has been the subject of bullying claims.
It is understood that she was advised about her conduct last year after a member of staff made a complaint against her.
A spokesperson for the Met Police confirmed to The Sun that an investigation was underway.
They added: 'We expect all officers to uphold the highest standards of behaviour and we take allegations extremely seriously and treat all parties fairly.'
The Daily Mail has contacted the Met Police for further comment.
It comes after Ms Mills's stalker Richard Jackson appeared at Worcester Magistrates' Court in June.
The assistant commissioner told the court the pensioner first targeted her when she was Chief Constable of West Mercia Police between 2021 and 2023.
The court heard Jackson had also loitered outside New Scotland Yard when she moved into her current role.
During this time Jackson bombarded her with emails and messages.
Colin Le Roux, prosecuting, said: 'He has no reason to email Ms Mills.'
'He has attended New Scotland Yard on two occasions.'
The court heard that Jackson was angry with West Mercia Police about an event in 2004, before Ms Mills had joined the force.
In a victim impact statement read out in court, Miss Mills said: 'It is literally giving me sleepless nights.'
'I dread walking from the station to New Scotland Yard and back in the evening. I'm hyper vigilant.'
'This has had a big impact on my lifestyle including me feeling unsafe in my home in case he finds out where I live.'
'I jump if the doorbell goes.'
Jackson was handed a two-year Stalking Protection Order, which bans him from attending New Scotland Yard unless he has a pre-arranged appointment.
