Armed police have arrested five men in connection with a shooting that left two brothers injured in what is believed to be a case of mistaken identity.
They were arrested on Saturday night in connection with the shooting of the men aged 47 and 46 at a house in Gloucester last Tuesday, Gloucestershire Police said.
The 46-year-old victim remains in hospital with a serious arm injury while his sibling has been discharged after suffering less serious injuries, a force spokesman said.
"Armed officers made the arrests in Barton Street in the city and on the A38 in Quedgeley yesterday evening," he said.
"Three Gloucester men aged 29, 26 and 21, a 27-year-old man from Cheltenham and an 18-year-old man of no fixed abode were arrested on suspicion of attempted murder and remain in police custody at this time."
The brothers were shot through the front door of a house in Falkner Street in the Tredworth area of Gloucester shortly before 4.15am on Tuesday.
On Friday, Detective Chief Inspector David Sellwood said: "This was an awful attack on two completely innocent people that could very easily have been fatal.
"I believe it's connected to a criminal dispute between two individuals and that the brothers have just been incredibly unfortunate to become embroiled in it.
"We've explained things to the intended victims and are working around the clock to trace the people responsible."
Detectives have appealed for information about a white Ford Transit van with the registration number MV52 ZZN that was in the Tredworth area at the time of the shooting.
