This is a very specific kill group
A man has been arrested on suspicion of murder after three men in their 80s - two of whom were believed to have been twins - were found dead.
The bodies of two 84-year-olds, named locally as Dick and Roger Carter, were found in Exeter on Tuesday, a day after that of a man named locally as Anthony Payne, aged 80.
Police said the level of violence used against all three had led them to link the deaths.
A 27-year-old man is in police custody.
