Detectives have warned people not to withhold information about two men wanted in connection with a 31-year-old man's death.
Dominic Bibby's body was found in Delph Close, Blackburn on Wednesday.
A senior detective said anyone withholding information about Glen Mould, 35, and Terrence Swallow, 36, would "face the consequences".
Both men are from Blackburn but Mr Swallow has links to Blackpool and Mr Mould to Cornwall.
A woman, 49, from Great Harwood, was arrested on suspicion of murder but was released without charge.
Det Supt Neil Hunter said: "I would urge anyone who knows either of these two men or where they might be to come forward and contact police as soon as possible.
"If anyone does know where they are or are helping them in any way I would like to warn people that they need to come forward as soon as possible and give police that information or they themselves will face the consequences."
He also repeated an appeal to the men to contact police, adding: "The longer you remain on the run, the worse the situation becomes."
