REGULATION 28:  REPORT TO PREVENT FUTURE DEATHS  

REGULATION 28 REPORT TO PREVENT FUTURE DEATHS 

THIS REPORT IS BEING SENT TO: 

1.  The Home Secretary

CORONER 

I am Philip Barlow, assistant coroner, for the coroner area of Northamptonshire

CORONER’S LEGAL POWERS 

I make this report under paragraph 7, Schedule 5, of the Coroners and Justice Act 2009 
and Regulations 28 and 29 of the Coroners (Investigations) Regulations 2013.

INVESTIGATION and INQUEST 

On 29 March 2018 I commenced an investigation into the death of Jack Knapman, age 
21. The investigation concluded at the end of the inquest on 13 December 2022. The 
conclusion of the inquest was a narrative conclusion that Jack died as an unintended 
consequence of taking dinitrophenol (DNP) for weight loss and body-building.

CIRCUMSTANCES OF THE DEATH 

1.  On 21 and 22 March 2018 Jack took a substantial quantity of Dinitrophenol (DNP) 

 for the purpose of losing weight and body-

building. He developed severe toxicity and was admitted to Northampton General 
Hospital. Despite treatment he suffered a cardiac arrest from which he could not be 
resuscitated and he died shortly after 1am on 23 March 2018.  

2.  The inquest received evidence from the National Food Crime Unit (NFCU) and from 
an expert in DNP poisoning. Most of the sale of DNP is on-line. The Food Standards 
Agency had become aware of Jack's purchase of DNP and there was an admitted 
delay in sending him a letter warning of the risk, although it was not possible to 
conclude that this made a material difference to the outcome. 

3.  The evidence was that, at the time of Jack’s death, there were delays in identifying 
sites selling DNP, getting them taken down, obtaining lists of customers, and 
sending warning letters to those customers. It is important to recognise that new 
policies are now in place at the NFCU which provide for more effective action and 
timescales.

CORONER’S CONCERNS 

During the course of the inquest the evidence revealed matters giving rise to concern. In 
my opinion there is a risk that future deaths could occur unless action is taken. In the 
circumstances it is my statutory duty to report to you. 

The MATTERS OF CONCERN are as follows.  –  

DNP is a highly toxic substance. It should never be used for human consumption. 
Nevertheless some people do use it to assist with weight loss and body-building. There 
have been many deaths associated with the use of DNP and it has been the subject of 
previous Prevention of Future Death Reports from coroners. The inquest heard that the 
number of deaths associated with the use of DNP has fallen but that the risk of further 
deaths remains for as long as it continues to be available and used for human 
consumption.

 The inquest was told that, following recent consultation, the Home Office intends to add 
DNP to the list of regulated poisons as an amendment to the Poisons Act 1972. The 
evidence at the inquest was that this would be a welcome action to help reduce its 
availability.  

However, after DNP is categorised as a poison it seems that it is not clear which 
organisation or Department of Government should have responsibility for monitoring and 
preventing its sale for human consumption. This would include identification of sites 
offering it for sale, investigation and enforcement. 

My concern is that a lack of clarity on this issue might delay an effective response to any 
site advertising DNP. This would clearly put lives at risk.

ACTION SHOULD BE TAKEN 

In my opinion action should be taken to prevent future deaths and I believe you and your 
organisation have the power to take such action.

Philip Barlow, 

Dear Mr Barlow, 

Thank you for your letter of 20 December 2022 in relation to the prevention for future 
deaths report following the inquest of Jack Knapman.  

I am very concerned about the tragic deaths being caused by the consumption of DNP as 
a dieting aid.  To this end, I have recently met with two bereaved families whose children 
tragically died from the consumption of DNP and have listened closely to their testimony.  I 
have carefully noted the contents of your prevention of future deaths report and agree that 
we must do as much as possible to safeguard those who may be vulnerable to harmful 
sales of DNP.  

As you note in your report, the Home Office has now laid legislation to regulate DNP as a 
poison under the Poisons Act 1972.  This will mean that, from 1st October 2023, DNP can 
only legally be sold to a member of the public by a registered pharmacist, and then only to 
a member of the public with a valid explosives precursors and poisons (EPP) licence 
issued by the Home Office.  We are not aware of any legitimate uses of DNP by the 
general public, and therefore this would act as an effective ban on sales to that group. 

The police are responsible for enforcing the Poisons Act 1972, and therefore will be 
responsible for investigating unlawful sales of DNP from 1st October 2023.  However, we 
recognise that some sellers, including those overseas, will do everything they can to flout 
regulations.  To this end, work will remain ongoing in the Home Office and across 
Government to do everything we can to crack down on the unlawful sale and use of DNP 
by working holistically to consider all aspects of the problem.  

                                                       Yours sincerely 

Rt Hon Tom Tugendhat MBE VR MP
