Police investigating the fatal shooting of a man at a caravan park in Somerset have arrested seven people.
John Broadway, 37, was held in Lichfield, Staffordshire on suspicion of murder, attempted murder and firearms offences.
Two women who were at the same location have been arrested on suspicion of assisting an offender, police said.
Later, another woman, 26-year-old Donna Broadway, handed herself into an Avon and Somerset custody centre.
She was detained on suspicion of assisting an offender.
The arrests follow a double shooting at the Chubbards Cross caravan park near Ilton, north of Ilminster, on Thursday night.
A 50-year-old man, Wilfred Isaacs, died, while a man in his 20s suffered "non life-threatening" injuries.
A post-mortem examination found that Mr Isaacs died of a gunshot wound to the body.
Charlie Broadway is being held on suspicion of murder and attempted murder
Three other people are also in custody, including 23-year-old Charlie Broadway who was arrested on suspicion of murder and attempted murder.
Detective Superintendent Andy Bevan said: "The investigation has so far involved a whole range of resources including a large team of detectives, neighbourhood policing teams, armed officers and the National Police Air Service helicopter.
"We'll continue to leave no stone unturned in our quest to establish the full circumstances behind this horrific crime.
"A vast amount of work is still taking place at the scene of the shooting as we're carrying out a large-scale forensic examination, in conjunction with ballistic experts, as well as other searches.
"The site remains closed off and these significant enquiries are likely to last several days.
"We're also continuing to look for the weapon used in this crime, which we believe to be a shotgun. If anyone knows where this weapon is they should call us immediately."
