A man has been charged with the murder of 27-year-old James Todd who was found dead at a flat in Clayton-le-Moors on Monday.
Mr Todd's badly decomposed body was found by officers at 12.15pm on Monday after neighbours reported an unpleasant smell coming from a block of flats on Rutland Close.
A post mortem examination revealed the cause of death to be a single stab wound to the heart.
Police say the stab wound was the only injury on the body.
David Fielding, 25, of Lynthorpe Road, Blackburn, was due appear before Hyndburn Magistrates Court on Friday charged with murder.
