Police have been conducting searches a week on from an attack that killed a dog walker in a south Suffolk village.

Mother-of-six Anita Rose died in hospital in Sunday, several days after she was attacked in Brantham while walking her Springer Spaniel last Wednesday morning.

A murder probe has been launched in the wake of the 57-year-old's death and additional police patrols have been visible in the village.

Ms Rose was found unconscious on a track near Rectory Lane at about 6.30am with a serious head injury.

She was taken to Addenbrooke's Hospital in Cambridge for treatment, but died a few days later.

Officers from Suffolk police were conducting searches of the area close to where Ms Rose was found between 5am and 8am on Wednesday.

Some officers remained in the village several hours later.

Leaflets have been distributed in a bid to shed more light on the attack and identify a suspect.

Officers have also been on trains between Ipswich and Manningtree on Wednesday morning to see if anyone has information related to the incident, with the route being the commuter line to the capital.

Two people have been arrested in connection with the murder probe - a 45-year-old man on suspicion of murder and a 37-year-old woman on suspicion of handling stolen goods.

They have both been released on bail until October 25.

Detective Superintendent Mike Brown said on Tuesday: "We completely understand and empathise with the concern some members of the Brantham community have expressed about the fact a male who has been arrested on suspicion of murder was subsequently bailed.

"It is important to understand that at times it may be necessary to make arrests in serious and complex investigations based on the evidence available at that time to fully understand the role individuals may have played in any offences identified. 

"As such, a person’s status in an investigation may change as the case develops which may result in options such as bail being used."
