Alan Wood murder has second appeal on BBC's Crimewatch
The torture and murder of a Lincolnshire man is to be featured for a second time on BBC One's Crimewatch programme.
Alan Wood, 50, died at his home in Lound, near Bourne, in October 2009. He was found with his throat cut and severe head injuries.
Police believe his attackers could have tortured him for his bank card PIN numbers.
The investigation first featured on Crimewatch in January last year.
Mr Wood's death has been the subject of several appeals and a £60,000 reward has been offered.
The new appeal will include investigation updates and new evidence that has come to light over the past 12 months, police said.
Det Supt Stuart Morrison, of Lincolnshire Police, said: "We will be working closely with the programme makers at the BBC over the next couple of weeks to ensure that we present the public with a comprehensive investigation update and show new evidence that we hope will move our enquiries forward."
Four men have been arrested in connection with Mr Wood's murder.
Three have been released from bail without further action while a fourth man, aged 20, remains on police bail.
