HN91

HN91 is the cipher given to a former undercover officer with the Special Demonstration Squad who was deployed against two groups in the 'last period of existence of the SDS'.Sir John Mitting, Applications for restriction orders in respect of the real and cover names of officers of the Special Operations Squad and the Special Demonstration Squad - 'Minded To' Note 11, Undercover Policing Inquiry, 21 June 2018.
The Chair of the Undercover Policing Inquiry, John Mitting, has ruled the Inquiry restrict both real and cover names of HN91 on the basis that they are currently serving in a 'valuable and sensitive role'.

==As an SDS undercover officer==
Joined police in early 1990s and into Special Branch in late 1990s. Late 1990s / early 2000s joined the SDS. Spent several months to build their legend.'HN91', HN91 Impact Statement, Metropolitan Police Service, 25 April 2017, published 9 July 2018 via ucpi.org.uk.
From risk assessment:Duncan Hodge, N91 - Risk Assessment, Metropolitan Police Service, 21 June 2018, published 9 July 2018 via ucpi.org.uk.
* On recruitment: N91 was first approached and then signposted towards other field officers to find out more about the unit.
* 'N91 was not explicitly promised anonymity. However it was explained to N91 that the SDS operated under conditions of absolute secrecy and they would be expected to maintain their anonymity. Nothing was put in writing for N91 but they say that it was made clear that this was a reciprocal arrangement.' 
* No arrests during deployment.
* 'The risk assessor notes that N91 felt they had good support from some other UCO operatives. N91 also states that they had visits with a psychiatrist during their time in deployment.'
Claims that a number of people associated with the group they targeted were violent, and are likely to still be. They state that if the inquiry revealed either cover or real name, they are likely to move abroad. They went on to say (in their personal statement):
:: I would never have become a UCO if I had been told that my anonymity would not be protected for life. I have always been discrete about my work and expected that this would operate both ways. I never engaged in any criminal acts while deployed and I did not have a relationship with any activists. After my relationship with my first partner ended, I started a new relationship towards the end of my deployment with my current partner, who was not involved in any activism or campaigning. For the first few months of this relationship, my current partner knew me by my cover name but I then told him/her that I was in fact a UCO and we have remained together since then. I did not have any other relationships while deployed. 
Risk assessor believes impact of revealing HN91's cover name is low to medium, and real name is medium to high.

In his 'Minded To' note, Mitting wrote:
:: HN91 was deployed against two groups in the last period of existence of the Special Demonstration Squad. None of the members of the target groups posed or pose a threat to the safety of HN91. But for the factor referred to below, I would not have made a restriction order in respect of the cover name. Evidence about the deployments must be received to permit the Inquiry to fulfil its terms of reference. Some, at least, of it will have to be given in closed session.
:: HN91 is a serving police officer, performing a valuable and sensitive role. If the cover name were to be published, there is a high risk that the real identity would be disclosed, in which event, HN91 could not continue to perform current duties. The risk of disclosure, by itself, would be likely to lead senior officers to transfer HN91 to other duties. It would not be in the public interest that this should occur. That interest outweighs the interests of the Inquiry in receiving public evidence about all aspects of the deployments of HN91.
:: Publication of the real name of HN91 is, in any event, not required to permit the Inquiry to fulfil its terms of reference. 
: There was also a closed note accompanying this.

:: It is submitted that I should not accept HN91 's "untested" assertion that during the deployment HN91 entered into one relationship in the cover identity (only) "albeit not, he says, with a protester". It is submitted that I "should not unquestioningly accept HN91 's account". I do not intend to do so. If appropriate, I can and will ask for the account of the officer's relationship to be confirmed by the person identified - the officer's long-term partner. It is also submitted that I have attached undue importance to the countervailing factor of the officer's current deployment. That is a matter of judgement for me. I stand by the judgement expressed in paragraph 13 of 'Minded to' note 11 and in the accompanying closed note.
