Murder arrest over 'vulnerable' man's death in Nelson
A man has been arrested on suspicion of murdering a "vulnerable" man who was subjected to a "sickening" and "targeted" attack, police said.
Christopher Moore's body was found at his home in Derby Street, Nelson, at about 22:00 BST on 20 June.
Police initially believed the 47-year-old's death was not suspicious, but a post mortem examination later revealed "significant" injuries.
A 38-year-old man is being held by officers and remains in police custody.
A Lancashire Constabulary spokesman said a precise cause of death had not yet been established.
Det Ch Insp Andy Cribbin said the attack had been "sickening due to the number of significant injuries and the manner in which they have been inflicted".
"I believe that he has been individually targeted due to his vulnerability and it is thought to be an isolated incident," he said.
"A number of his injuries are older in age and likely to have been caused in the weeks leading up to his death."
