Carrick, 47, had previously been charged with 44 offences against 12 victims including rape, coercive and controlling behaviour and sexual assault.
He has now been charged with a further nine offences in relation to a thirteenth victim.
The charges are as follows:
- Six counts of rape;
- False imprisonment;
- Indecent assault;
- And possession of a firearm with intent to cause fear of violence.
The charges relate to incidents alleged to have occurred in 2003 that were reported to police in July 2022, and are part of an ongoing investigation by Hertfordshire Constabulary.
The allegation in relation to possession of a firearm predates Carrick’s service in an armed policing role, the Met said.
He will appear at Westminster Magistrates’ Court on Wednesday, November 30. He continues to be remanded in custody.
Carrick was initially arrested by Hertfordshire Constabulary in October 2021, and immediately suspended. Prior to his suspension, he was attached to the Parliamentary and Diplomatic Protection Command.
A Met spokesperson said: “We recognise that these are extremely serious and concerning allegations.
“Referrals have been made to the Independent Office for Police Conduct (IOPC) as the investigation has progressed.
“The Met’s Directorate of Professional Standards (DPS) continues to monitor developments closely and will provide whatever support it can to Hertfordshire officers.
“National regulations dictate that any misconduct proceedings must await the outcome of the criminal case.”
