The death of a woman who was killed in an explosion alongside a man at her home is being treated as a homicide, police said.
Jo Shaw, 35, was killed in the blast at the house in Bristol on Sunday morning, which also saw her former partner, Ryan Kelly, 41, suffer fatal injuries.
Avon and Somerset Police said a referral would be made to the Independent Office for Police Conduct due to previously reported domestic-related incidents.
Three other people, including a child, suffered minor injuries during the incident at a house in Sterncourt Road.
Superintendent Matt Ebbs said: “Jo’s death has been officially recorded as a homicide based on the information known to us at this time. We are not looking for anyone else in connection with her death.
“We would like to reassure the public there is not believed to be any wider risk to safety and this is not being treated as terrorism-related.
“As previously stated, we believe the cause of the explosion to be deliberate. Analysis work of the explosive device has not yet been completed.”
Residents living near the scene were evacuated and a cordon was put in place to allow Army bomb disposal experts to examine the site.
Avon and Somerset Police said a call was received from a person inside the property at 6.17am reporting a domestic-related incident, saying a man they knew had forced entry to the house.
The caller stayed on the line while police were dispatched to the house, and at 6.30am the caller told the police the man was believed to be in possession of an explosive device.
Around two minutes later, an explosion occurred at the property, in which Ms Shaw and her former partner died.
The first officers arrived at the property at 6.34am and were joined by the fire and ambulance services shortly afterwards.
“We know everyone’s thoughts and sympathies will be with her devastated family,” Mr Ebbs said.
“Specially-trained officers are providing them with updates and support.
“We recognise there is significant interest in what happened, but at the centre of it, there are many people grieving and we would please ask everyone to respect that and give them the privacy they want.”
Officers worked with Bristol City Council to evacuate people staying in neighbouring properties as a precaution and a temporary rest centre was set up.
Extensive searches were carried out by the Army to ensure the area was safe before the cordon was reduced on Sunday night and almost all residents were allowed to return home.
A search of an address in Speedwell linked to Mr Kelly concluded over the bank holiday weekend. No evacuations were required at that location.
Mr Ebbs added: “Police activity continues to be carried out at the property in Sterncourt Road and we expect this will take several days to be completed.
“We will share all details of our enquiries with the coroner so they can make a final determination around how the deaths occurred in due course.
“Officers remain in the area and people can speak to them if they have concerns they wish to discuss with us.
“Finally, we would like to reiterate our thanks to emergency services, other agencies and volunteers for their support over the weekend.
“This remains a challenging and complex incident, and we are ensuring our officers and staff have access to any support they need.”
