Detectives investigating the murder of Corby businessman David "Les" Ross are making a fresh appeal for witnesses on the first anniversary of his death.
His body was discovered in a hotel in Corby in December last year.
Detectives believe he may have been targeted by organised criminals who were trying to take over his involvement in a local nightclub.
Detective Chief Inspector Martin Kinchin said. "This has been a challenging case but we do believe that Mr Ross's death is linked to his involvement in the club. That isn't to say there is anything untoward about the club, we believe someone was trying to take over his involvement in Rubix."
