Contact with man prior to his death - Hertfordshire Constabulary, September 2016

Investigation summary:

On 18 September 2016 a man, Mr A, was struck in the head by another man, Mr B, after leaving a nightclub in Watford at around 3am. Mr A was left unconscious. Two Hertfordshire Constabulary officers saw Mr A and approached. Mr A’s friends told the officers that he was “a little drunk”. However, another man informed one of the officers that he had seen Mr A being assaulted. Mr A regained consciousness and left the scene. He did not make any allegations in relation to the assault.

Later, Mr B allegedly told a third police officer that Mr A had attacked him. Mr A’s friends went over to the police officer to tell him that it had been Mr B who had hit Mr A. The police officer could not recall the incident.

Mr B was not arrested and, a short time later, struck Mr A in the head again. Mr A collapsed to the ground, lost consciousness again and stopped breathing. Police officers were informed of the incident and started giving him CPR while waiting for the ambulance. Mr A was taken to Watford General hospital, where he was pronounced dead some hours after.

CCTV of the first assault was available, but not identified until after Mr A died. Mr B was eventually tried and found guilty of manslaughter.

The IPCC took witness statements and analysed CCTV footage of the incident. One officer was declared a subject of the investigation. A case to answer for misconduct was found due to the manner in which she dealt with the witness who informed her that Mr A had been assaulted.

The force dealt with this through management action with the officer, including identifying learning areas and a development action plan.
