The shooting of two brothers in the Tredworth area of Gloucester earlier this week is believed to be a case of mistaken identity, officers have confirmed.
Detectives investigating the case say that the two men who were shot through the front door of a house in Falkner Street shortly before 4.15am on Tuesday (April 2) were not the intended targets.
One of the victims, a 47-year-old man, remains in hospital with a serious arm injury while his 46-year-old sibling has been discharged after suffering minor injuries.
Police have spoken to those living at an address they believed the offenders meant to target and safety measures have been put in place to help protect those people.
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 incredibluy 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.
"This investigation is complex. It's demanded a very methodical approach and painstaking work by my team of officers so I'm grateful to them and the public for their cooperation and patience as we continue our work."
Gloucester Superintendent Emma Ackland added: "The local policing team is working very closely with the investigation team to ensure people in Tredworth feel safe and protected.
"There is no information to suggest any threat to the public but we understand that the incident is unsettling and disturbing.
"That's why I want people to know that community and firearms officers remain in the area and will do for the foreseeable future.
"If you have any concerns please don't hesitate to make contact with officers from the local policing team, ring us via the 101 number or email Gloucester.lpa.communities@gloucestershire.police.uk."
Anyone with information is urged to call 101, quoting incident 36 of April 2.
