The Independent Office for Police Conduct (IOPC) are investigating the actions of Humberside Police prior to the death of a man in Driffield.
Shane Gilmer, 30, was fatally wounded after being attacked at his home in Southburn on 12th January. His partner, Laura Sugden, was also injured.
Anthony Howarth (also known as Anthony Lawrence), their neighbour and the man suspected of the murder of Mr Gilmer and the attempted murder of Ms Sugden, was found dead in North Yorkshire the following day.
The IOPC understand, at this time, that Mr Gilmer and Ms Sugden made a number of reports to Humberside Police regarding the alleged actions of Anthony Howarth from January 2017.
The investigation will look at a number of reports made prior to the incident on 12th January 2018, including the nature of the contact with police, how this was recorded and how the force responded.
The force’s search for 55-year-old Howarth or the circumstances of his death are not part of the investigation.
IOPC Regional Director for the North East, Miranda Biddle, said: “We carefully considered the referral from Humberside Police before beginning our investigation, making the decision to look at the reports by Mr Gilmer and Ms Sugden and what, if any, contact the force had with Anthony Howarth dating back to January 2017.
“We have met with Mr Gilmer’s family and with Ms Sugden, to discuss our investigation, and they will be regularly updated on its progress.
“I am confident that our investigation, and of course the coronial proceedings to come, will bring some clarity to the circumstances of this horrific murder and attempted murder.”
