At least 12 serving police officers are being investigated over their conduct in relation to policing and the murder of Sarah Everard.

On Friday (July 9), the Independent Office for Police Conduct (IOPC) said it had served 12 officers from several forces with "gross misconduct or misconduct notices" regarding multiple investigations ongoing that are linked to the death of Sarah Everard and the conduct of PC Wayne Couzens, who pleaded guilty to her murder.

The misconduct notices have been served over a variety of cases, including "circumstances surrounding how PC Couzens sustained head injuries in custody on March 10-12," a spokesperson for the IOPC said.

Other investigations are linked to the Metropolitan Police's alleged failure to investigate two instances of indecent exposure linked to PC Couzens prior to Sarah Everard's death, in London in February earlier this year.

Two officers are being investigated for possible breaches of professional standards at misconduct level relating to that investigation.

Similarly, Kent Police are being investigated over a separate instance of indecent exposure in Kent, also linked to Couzens, that dates from 2015, the IOPC said.

Another investigation relates to the sharing by a Met Police officer of an "inappropriate graphic with colleagues via social media" who reportedly later "manned a cordon at the scene of the search for Ms Everard", the IOPC said.

Three officers are being investigated for gross misconduct in that instance.

Finally officers from "a number of forces" face IOPC probes related to potential breaches in the standards of professional behaviour "while sharing information linked to the prosecution of PC Couzens via a messaging app".

One officer has been served with a gross misconduct notice and another six have received misconduct notices.

IOPC Regional Director Sal Naseem said: "Our sympathies remain with the family of Sarah Everard and everyone affected by her death in such shocking circumstances.

"We share the horror that many will feel, knowing that Sarah’s killer was a police officer who had taken an oath to uphold the law and protect life and property. The offences Wayne Couzens has admitted add up to the worst betrayal of the public’s trust.

"We are still investigating a number of matters linked to PC Couzens and Sarah’s death, and we are working hard to bring those to as swift a conclusion as possible."
