A man who died following an altercation between two dog walkers had been appointed an MBE and could often be found “pounding the pavement” for the Labour Party.
Retired civil servant Ralph Baxter, 74, died while walking his dog in Roade, Northamptonshire, on Wednesday.
A 27-year-old man arrested on suspicion of murder has been released on bail.
In a tribute, Mr Baxter’s family said he was a “loving husband, step-father, step-grandfather, brother, and uncle”.
A post-mortem examination into his death carried out at Leicester Royal Infirmary came back as “unascertained”.
Mr Baxter had been walking his dog, Bertie, in Hyde Road at about 16:20 BST when he was assaulted.
Residents said there had been a clash between his pet and a larger, husky-type dog.
