A man has been arrested after a woman in her 70s died in an attack in an Exeter park.
Officers were called to Ludwell Valley Park, in the Wonford area of Exeter, at around 4pm on Saturday following reports a woman had been seriously assaulted.
The victim, a local woman, was declared dead at the scene.
Her next of kin have been informed and are being supported by specialist officers.
A man in his 30s from the Exmouth area was detained by armed officers in the city centre at just after 9.30pm on Saturday following an appeal.
Superintendent Tom Holmes, of Devon and Cornwall Police, said: "Whilst this is a positive update, a major response remains in place and our investigation into this murder continues.
"Tonight we issued an image of a man we needed to identify.
"Now that we have a man in custody we no longer need the public to share this appeal; please do not speculate on the identity of the suspect or the circumstances surrounding this matter."
