A man and a woman arrested within hours of the shootings will face no further action, say police, though a 66-year-old man remains in custody.

The pair were killed within 40 minutes in two villages just six miles apart in what police called a "targeted, planned" attack.

Three people have been arrested, with a shotgun recovered, as police said they were investigating whether the shootings relate to a custody battle.
