A double murder investigation is underway after a man and woman were found stabbed to death at a home in Blackburn today.

Officers were called by the North-West Ambulance Service at 8.22am (Monday, September 7) to an address in Hardman Street where the pair were pronounced dead at the scene.

Lancashire Police said a man in his 40s has been arrested on suspicion of murder and remains in custody at this time.

The force said the man and woman have not been formally identified at this stage. A Home Office post mortem examination will take place in due course.

A police spokesperson said: “We have a dedicated team of officers assigned to this case, carrying out CCTV, house-to-house and forensic enquires in the area.

“There is currently a scene on at the property and will remain in place over the coming days.

“You will continue to see an increased police presence in the area, as we conduct enquiries and provide reassurance. If you have any information or concerns, please stop one of our officers for a chat.

“Whilst this is a fast-moving investigation, we are at the early stages of establishing exactly what has occurred and why.

“Detectives are continuing to work to establish a motive for this tragic incident; however, we don’t believe there is a wider threat to the community.

“We will provide further updates when it is appropriate to do so.

“In the meantime, if you saw or heard anything suspicious in the area over the last 24 hours, or have captured any CCTV, dashcam, mobile phone or doorbell footage that could help us with our enquiries, please make contact with our officers as soon as possible.”
