A man has been arrested on suspicion of the murder of a woman who was attacked while walking her dog.
Anita Rose, 57, left her house to take her springer spaniel Bruce for a walk at about 5am in Brantham, Suffolk, on 24 July.
The mother-of-six was found unconscious with serious head injuries on a track road near the sewage works and railway line near Rectory Lane at about 6.25am by a cyclist.
She died four days later at Addenbrooke’s Hospital in Cambridge.
Suffolk Police said the 55-year-old man was arrested in Ipswich and remains in custody.
Specialist officers are supporting Ms Rose’s family and keeping them updated on the investigation.

Officers said Ms Rose’s dog, who was still with her, was not harmed.
It was reported in August that a post-mortem failed to find the cause of Ms Rose’s death, after which Suffolk Police said officers were continuing to investigate the case as murder.
Crimestoppers has offered a £20,000 reward for information that leads to the arrest and conviction of anybody involved in the death of Ms Rose.
