Our thoughts are with the family of the those found at the property grieving such a traumatic loss.
“We would like to thank the community for their help and will continue to provide reassurance patrols in the area. A cordon will remain on at the address whilst we finalise our detailed examination of the scene.”
The incident has been referred to the Independent Office of Police Conduct (IOPC) due to a 999 call made from a man at the address prior to the incident, which did not result in the deployment of officers and police contact at the address on 14 December, relating to a missing person enquiry.
