A man has been arrested on suspicion of murder after two people were found dead in a house in Blackburn.

Lancashire Police said the bodies of a man and woman were found at the home in Hardman Street in the town at about 08:20 BST, and a man aged in his 40s had been arrested.

The man and woman, who have not been named, were both pronounced dead at the scene.

Police said they were unable to confirm the victims’ age but local residents told the BBC they were elderly.

Police said a dedicated team of officers had been assigned to the case, and were carrying out CCTV, house-to-house and forensic inquires.

The crime scene would “remain in place over the coming days”, the force said.

Officers have also appealed for anyone with any information to contact them.

A spokesman said: “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.

“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.”

Local councillor Terri Mahmood told the BBC: “The community is in shock.

“The family is deeply, deeply upset, it’s shocking to them.

“The women are in tears.

“We don’t want to speculate, we just want the police to investigate.”
