Three men arrested over the torture and murder of a Lincolnshire man have been released from bail without further action.
The men, aged 18, 35 and 43, answered bail on Tuesday over the death of Alan Wood, who was killed at his home in Lound, near Bourne, in October 2009.
Mr Wood, 50, was found with his throat cut and severe head injuries.
Police believe his attackers could have tortured him for his bank card PIN numbers.
Mr Wood's death has been the subject of several appeals, including one on BBC One's Crimewatch programme, and a £60,000 reward has been offered.
He was last seen alive on 21 October 2009 at his local pub the Willoughby Arms, in the nearby village of Little Bytham.
A fourth man, aged 20, remains on police bail.
