BBC Crimewatch appeal over murder of 'gentle old boy'
A family has appealed for help after a "gentle old boy" was murdered in a savage attack during a botched burglary in Cambridgeshire.
Llywelyn Thomas, 76, was found dead at his home in Chittering, near Cambridge, on 18 December.
Richard Thomas, his son, has urged people with information about the crime to contact police.
The case is being featured on the BBC's Crimewatch programme.
Richard Thomas said: "Whoever is close to these people should see what their son, their daughter, their father, their brother, their friend has done because they may have done it before. They may do it again.
"If neither of those is true, then they just need to see what they've done to one gentle old boy."
Det Ch Insp George Barr said: "This was a savage attack upon Llywelyn.
"We think he would've been punched to the face. He would've been struck around the back of the head."
Rewards totalling £50,000 have been offered for information leading to the conviction of those responsible.
The family is offering £20,000, Crimestoppers a further £10,000 and Cambridgeshire police £20,000.
Detectives believe retired farmer Mr Thomas was killed on 17 December in a botched burglary.
He had moved to the area 12 years ago from Wales to be nearer his family.
