Part of a series on undercover police officers
'HN4'
Alias:	unknown
Deployment:	late 1980s / early 1990s
Unit:	Special Demonstration Squad
Targets:	one group, unknown

HN4 is the cipher given to a former undercover officer with the Special Demonstration Squad who was deployed into two branches of one group in late 1980s and early 1990s. The Chair of the Undercover Policing Inquiry, Sir John Mitting, has indicated he will restrict HN4's real and cover names, but a final decision has yet to be made (October 2018).

As an SDS undercover

According to HN4's Impact Statement, HN4 was a Metropolitan Police Special Branch officer who had worked on the Animal Rights desk there, before joining the Special Demonstration Squad as an undercover officer. He was deployed in late 1980s/early 1990s into two branches of one group. He denies having any sexual relations with those he targeted. HN4 left the police in the 1990s, having medically retried, and has taken up another career.

Writing of his time undercover, HN4 says:

When on the SDS/SOS we were told to keep a low profile. We were certainly not to discuss our work in public or even to colleagues. I was told.... that my details would never come out. I also recall [a manager] stating to us that a prosecution would be discontinued if it relied on an undercover officer's evidence.

The risk assessment for HN4 states:

N4 spent approximately six months in the back office developing the cover identity and learning fieldcraft.

N4 was given an assurance of anonymity during the interview stage and this assurance was also repeated to N4's partner. To paraphrase the recruiting senior SDS manager, "prosecutions would be dropped if they would lead to the compromise of UCOs". The same senior SDS manager spoke to N4's partner about the long hours N4 would be expected to work and they were also warned of character changes that could occur during the deployment and the need to share issues with each other.

Also according to the assessment

N4 was tasked to report on the numbers, members and intentions of the targeted group and the threat posed by them at public order events.

Specific tasking when required was given at the twice weekly meetings on Monday and Thursday which all officers were expected to attend, barring exigencies. N4 does not remember being specifically tasked other than in relation to a particular demonstration.

N4 recalled the name of nine key associates. When asked about individuals of concern, N4 stated that s/he had no concerns about physical violence from any of the people mentioned but some might feel a sense of betrayal.

N4 stated categorically that s/he did not enter into any sexual relationships during the deployment. N4 and N4's partner had been warned by the SDS manager who recruited N4 of the dangers of this, and there was no encouragement to form sexual relationships as a means to gather intelligence. N4 recalls that there was information about the dangers of overly close relationships in the Tradecraft binder kept in the SDS office.

N4 was arrested during the deployment, charged and convicted. N4 was subject to internal discipline. Representations were made by Special Branch management in support of N4.

N4 could not recall any prominent successes arring out of the deployment and there is nothing recorded on filed

In the Undercover Policing Inquiry

• 11 May 2018, directed that anonymity applications for HN4 were to be filed by 31 May 2018 for both the MPS legal team and the Designated Lawyers team.

• 21 June 2018: announced that the Chair of the Inquiry, John Mitting was 'minded to' restrict the real name of HN4, but wanted to consider the application to restrict the cover name at a closed hearing to give the officer 'the opportunity to respond' to the Chair's Minded To decision.

According to the June 2018, 'Minded To' note from Mitting:

To permit the terms of reference of the Inquiry to be fulfilled, it is at least likely that evidence of and about the deployment must be given in public. This will require the evidence of HN4 to be provided or given in public as well.

HN4 suffers from two medical conditions. In the opinion of Professor Fox, who has prepared a report on HN4 dated 16 April 2018, publication of the real name would be likely to have a severe and irreversible impact on one of them. I accept that opinion. It is not necessary to permit the Inquiry to fulfil its terms of reference that the real name of HN4 should be published... His opinion on the effect of publication of the cover name and/or of the provision of giving of evidence by HN4 is less clear. It is an issue which must be explored in a closed hearing.

A closed note accompanies these reasons.

• 30 July 2018: following a closed hearing, Mitting is minded to restrict real and cover names on the basis of the 'minded to' of 21 June, and closed reasons.

A final decision on the manner in which evidence is to be provided and given by HN4 will not be taken until the documentary evidence relating to the deployment has been obtained and analysed.

• 13 September 2018: following responses to the 'Minded To', open material relating to the publication of the real name will be published, with date for responding.

• 3 October 2018: material released:

• Open Application from Metropolitan Police to restrict HN4's real name, 29 May 2018.
• Open Application from Designated Lawyers on behalf of HN4 to restrict real and cover names, 31 May 2018.
• Impact Statement from HN4, 30 May 2018.

"In combination the documentary 'True Spies', the revelations of Peter Francis (and the fact that I am known to him...) the launch of the Inquiry... have all increased my anxiety and paranoia and in particular my fear of media intrusion."

"I am sad and angry about the length of time this Inquiry is taking and that I will have to go on living with these feelings for years to come. I didn't have any sexual relationships whilst deployed and feel angry towards the undercover officers whose behaviour has led to this Inquiry."

"In my view the anxiety I suffer from is directly related to this Inquiry and my work on the SDS/SOS."

• HN4 Medical gist - précis of two reports by Prof. Fox of 16 April and 9 July 2018 into health of HN4, which refers to HN4 having two medical conditions going back to the 1990s and that if there was a release of HN4's cover name it would cause an irreversible decline in the former undercover's health.
