A Nottinghamshire Police officer who supported the family of Warsop murder victim Clifford Collinge was having an affair with the solicitor of one of the accused, a misconduct hearing was told.
Detective Constable Peter Surgay was a family liaison officer following the murder of Mr Collinge (pictured) in 2011.
Mr Surgay’s relationship with Ashfield-based solicitor Deborah Bell was kept secret as his wife also served with Nottinghamshire Police, the hearing was told.
The detective is alleged to have been involved in what was described as “volatile” on-off sexual relationship with Ms Bell since 2009.
The solicitor, who regularly appears at Mansfield Magistrates’ Court, then went on to represent Stephen Shreeves - one of the three accused of the murder of Mr Collinge.
Shreeves is currently serving a life sentence after being found guilty of murder.
Widow Charlotte Collinge was initially found guilty of murder but was later acquitted following a retrial last year.
Mr Surgay is alleged to have not reported the nature of the relationship which, it was argued, could have compromised a major investigation.
He is also facing a separate allegation of gross misconduct for sending “appalling” text messages to Ms Bell after the breakdown of their relationship.
The hearing is expected to conclude today (Wednesday, August 3).
