An armed Metropolitan Police officer, identified as NX121, has been charged with the murder of black rapper Chris Kaba in south London. Kaba, a 24-year-old expectant father, was fatally shot by a police marksman during a vehicle stop on 5 September 2022. Armed officers had been covertly following the vehicle, flagged by Automatic Number Plate Recognition as connected to a firearms incident. After the shooting, no firearms were found in the vehicle. The officer was initially placed on restricted duties but later suspended. The decision to charge the officer followed a six-month investigation by the Independent Office for Police Conduct (IOPC). NX121 is set to appear in Westminster magistrates’ court. Kaba's family welcomed the charging decision, expressing hope that justice would be served. The police federation expressed concern about future implications for officers involved in dangerous roles. This case echoes past instances where armed Met officers faced murder charges over fatal shootings while on duty.
