Kareem’s request to be allowed to feature in the show was turned down but she went on the show nonetheless which has now triggered an internal investigation.
The 29-year-old, who joined the force as a police constable in 2015, has been filmed allegedly having sex on-screen with fellow contestant Ekpata Gedoni, 31 an action that has further incensed her colleagues and bosses who said it brings the force into disrepute. The show producers have denied it happened.
A Met Police spokesman said, "A Pc, attached to the Met's transformation command, requested permission to take part in a reality television entertainment show in Nigeria. Permission was not given.
"The Met is aware that the officer has since appeared on the show without authority.
"The Directorate of Professional Standards has been informed and will be carrying out an investigation into the circumstances.
"The Met does not support the officer's appearance nor does she represent the Met whilst appearing on the show."
The force added that any officer found to have breached police standards of professional behaviour could face misconduct proceedings.
Khafi Kareem’s management company has risen to the defence of the BBNaija Season 4 housemate saying she remains a "proud black female officer".
In a statement released on her official Instagram handle on Tuesday, the management wrote, "Khafi is a proud black female officer who prides herself in her work and has dedicated her youthful years protecting and serving with her many skills which include the ability to speak at least five international languages."
