==As a SDS undercover==
Joined MPS in late 1970s and joined Special Branch in early 1980s.'HN97', HN97 Impact Statement, Metropolitan Police Service, 28 May 2018, published 9 July 2018 via ucpi.org.uk.
Deployed in 1980s, but resigned from Metropolitan Police in the 1990s. The group deployed posed no real risk to public order or to HN97 personally.
Before being formally accepted by SDS was visited at home; an assurance of anonymity was provide to HN97 and his wife.
HN97 says they had no relationships while deployed, and was not arrested. The risk assessment notes that HN97 describes good support from colleagues, including regular meetings with other undercovers and managers.Graham Walker, N97 - Risk Assessment, Metropolitan Police Service, 22 June 2018, published 9 July 2018 via ucpi.org.uk.
The risk assessment notes that though there will be 'overwhelming interest' in the deployment, the risk level is high, even if only cover name is disclosed. They are also concerned that if their real name was released it would 'destroy my current career'.
An extra note from the Inquiry stated:Inquiry's gist of additional information from HN97’s closed risk assessment, Undercover Policing Inquiry, 2018, published 9 July 2018. 
:: Much of the intelligence reporting by HN97 at an early stage of the deployment is not available from within MPS Special Branch records. Efforts to retrieve material from other locations has resulted in some, possibly all, contemporaneous records being gathered.

In his 'Minded To' note, Mitting wrote:
:: HN97 is in his 60s. His deployment is of significant interest to the Inquiry and must be explored in detail to permit the terms of reference to be fulfilled. The group into which he was deployed posed no risk to public order or to him personally. Despite that, there would be a real risk, which cannot be precisely quantified, from sources which cannot now be identified, to his safety if his real or cover name were to be published and/or if certain details of his deployment were to be made public. Balancing the public interest in providing as much public information as possible about it against the need to protect his own safety and/or the public interest in ensuring that his real identity is not disclosed when evidence about his deployment is received will be a delicate and difficult task, which must be addressed soon.
::The restriction orders which I am minded to make are necessary to avoid a risk of harm to HN97 and to avoid impairing the effectiveness of the Inquiry.... They are also necessary to avoid an unjustified risk of interference in the right of HN97 to respect for an aspect of his private life - physical integrity - and of his and his family's right to respect for private and family life...

:: It is submitted that the risk assessment is internally contradictory. It is not. The risk assessor's assessment, which I accept, is that disclosure of the real or cover name of HN97 creates a risk, which cannot be precisely quantified, of extreme, life-threatening, violence. The issue is more fully considered in the closed risk assessment and in the closed note which accompanied 'Minded to' note 11. I have already acknowledged the difficulty in reconciling the public interest in the receipt of evidence about his deployment and the need to protect his safety. Meanwhile, I have decided that there should be a restriction order in respect of both his real and cover name.
