Dear Dr Radcliffe

| am writing on behalf of the Commissioner in response to your Regulation 28 Report to
Prevent Future Deaths dated 23 May 2019, following the conclusion of the inquest into the
death of Tyereece Johnson. In Deputy Assistant Commissioner Matthew Horne’s absence, |
will be responding in my role as OCU Commander for the Directorate of Professional
Standards.

In drafting our response we_have consulted with the relevant subject matter experts,

principally: Superintendent Service Delivery for Met Command and Control
(MetCC) ae ead of Support for MetCC and Chief Inspector Lisa Maslen, Met
Grip, MetCC.

Response to Matter of Concern:

The first CAD messages gave an approximate age of the riders of the moped (aged 15
to 16). However this was not passed on to the team in the Police Control Centre who
were formulating tactics to bring the moped to a stop. All witnesses from the police
control room and police helicopter agreed that the age of the riders was a relevant
factor to take into account when formulating a risk assessment in order to inform their
tactical decision making. (However | did not find that it caused or contributed to the
death in this instance). Action should be taken to ensure such important information
is made available to all relevant staff who are formulating risk assessments in this type
of scenario.

Since 2016 a number of changes have been made within Met Command and Control (MetCC).
There is a now a dedicated pod for police pursuits and follows as occurred here, which consists
of the following six roles;

1. Intop Channel Operator (Interoperability — a dedicated channel to allow neighbouring
forces to have a set of radio channels that could easily be used for cross-border
incidents, especially pursuits. Each police force has at least two interoperability
channels which each surrounding force has access to).

2. Channel 5 Operator (This is the support function for the Pan London radio channels.
In the event of a pursuit/follow on Intop, the Channel 5 operator can help the Intop
operator with typing whilst the operator speaks, assigning units to the incident).

Whilst each has a number of responsibilities, it is for the Pan London Supervisor to take overall
control of the pursuit/follow. Their role is to constantly risk assess the situation based on the
information and intelligence available using the National Decision Model.

Due to the dynamic nature of incidents it is for the Pan London Supervisor to determine who
is best placed at that time to carry out any additional intelligence checks and to continue to
assess and task as appropriate throughout the incident.

The MPS considers that the changes implemented since 2016 are sufficient, however as a
result of this Regulation 28 Report to Prevent Future Deaths, MetCC led by Superintendent
Gary Warby in charge of Service Delivery, will take the following action;

e Review the roles and responsibilities of the pod to ensure they are maximising
information/intelligence opportunities.

e Consider whether there should be a mandatory checklist of indices at the start of a
pursuit e.g. Police National Computer, Computer Aided Despatch (CAD) incidents
including linked CADS, and Integrated Information Platform.

e Ensure Pan London courses and refresher training includes an input on information
and intelligence gathering.

This review will be completed by 31%t October 2019.
In Conclusion

In the last couple of years MetCC has created a dedicated police pursuits pod. This contains
the necessary resources to support the Pan London Supervisor, who has overall control of
pursuits/follows, with the information and intelligence required to risk assess the incident using
the National Decision Model. MetCC believes this is sufficient to address the matter of concern
raised by the Coroner, however they seek to improve their practices further and will conduct
a review of the roles and responsibilities contained within the pod to ensure they maximise all
available information and intelligence opportunities. This review will be completed within the
next four months.

| trust this provides the reassurance that we have considered the point you have raised and
that we have made improvements and continuously seek to do so.

Yours sincerely,

Beotobleht

Peter Holdcroft
Detective Chief Superintendent
