Two children, Nuria Sajjad and Selena Lau, died and more than a dozen people were injured after a Land Rover smashed through a fence at The Study Prep school July 2023. Several others were injured.
The IOPC says it’s also investigating allegations officers provided false and misleading information to those affected.
An initial investigation into the collision by the Met’s Roads and Transport Policing Command resulted in a direction from the Crown Prosecution Service that the driver should face no further action.
After concerns were raised by the families of Nuria and Selena about the outcome, it was agreed the Met’s Specialist Crime Review Group would carry out a review of the investigation. That review identified further lines of enquiry and a decision was subsequently taken to launch a reinvestigation in October 2024, under the Specialist Crime Command.
In July 2025 the Met received a complaint from the families about various aspects of the initial investigation. Separately, through the course of their enquiries, the team reinvestigating the collision had also identified a number of issues relating to the first investigation. The Met’s Directorate of Professional Standards made a referral to the IOPC which confirmed it would independently investigate the matter.
As part of their investigation, the IOPC is investigating complaints against 11 officers.
Four serving officers and one former officer have been served with notices informing them that their conduct is being investigated at the level of gross misconduct. These officers are a commander, detective chief inspector, detective sergeant, detective constable, and a former detective inspector.
A further two officers, detective constables, are under investigation for misconduct.
The serving of notices does not mean that misconduct proceedings will necessarily follow.
During the Met’s reinvestigation, the team pursued new lines of enquiry and arrested a woman last year. Following these enquiries, officers submitted a full file of evidence to the CPS on 17 March 2026. Prosecutors continue to consider this evidence and will be making a decision in due course.
Commander Charmain Brenyah, who leads the Met’s Roads and Transport Policing Command, said: “Our thoughts remain with Nuria and Selena’s families, as well as everyone who has been impacted by this terrible tragedy. We understand this prolonged process has compounded their grief and suffering.
“It is right that our initial handling of this incident be independently scrutinised, and we will provide every assistance to the IOPC as their investigation continues.”
IOPC director Amanda Rowe said:
“Our thoughts are with the families and friends of Nuria Sajjad and Selena Lau and all those who were affected by the tragic incident in July 2023.
“We are investigating complaints made against 11 Met Police officers over their handling of the initial investigation into the road traffic incident, in which the two children sadly died and multiple other people were injured at The Study Preparatory School in Wimbledon
“We began our investigation in August 2025 following a referral from the Met Police of complaints made on behalf of individuals who were affected by the incident.
“The complaints relate to concerns about the standard of the investigation, including its management and direction, the conduct of the investigation team, and their engagement with the victims. We are also investigating allegations that Met officers provided false and misleading information to those affected and whether the officers’ treatment of those affected was influenced by their race.
“We have now served notices advising four serving officers, whose ranks are commander, detective chief inspector, detective sergeant and detective constable, and a former detective inspector, that their conduct is being investigated at the level of gross misconduct.
“Two detective constables are being investigated at misconduct level.
“Our investigation is ongoing and should any further conduct issues be identified then officers will be served notices.
“All officers served notices will be interviewed in due course. The serving of notices does not mean that proceedings will necessarily follow.
“As part of our inquiries, IOPC investigators have met with the complainants as well as the officers leading the Met Police’s reinvestigation of the road traffic incident. They, along with the Met Police’s Directorate of Professional Standards, have provided relevant material and documentation which IOPC investigators are reviewing.
“We have spoken to the complainants about our work and will continue to provide regular updates to all parties involved. At the end of our investigation, we will decide whether any officers have a disciplinary case to answer in respect of the conduct allegations.”
