Thames Valley Police is appealing for information in connection with the shooting of a man at an address in Aylesbury on Wednesday morning.
Officers were called to an address in Stour Close in the Walton Court area of the town shortly before 10am after members of the public reported hearing three gunshots.
On arrival in Stour Close, officers made their way into a residential property, where they discovered a 33-year-old man who had sustained gunshot wounds to his arms and head.
The man was taken to hospital where he is currently in a critical condition.
Given the nature of the man’s injuries, armed response officers were deployed to the scene to help trace the person responsible.
Det Ch Insp Gill Wootton said: “At this stage it is far too early to speculate around the motives behind this incident. However, we do not believe it was a random one.
“We are at a very early stage in our enquiries and are appealing for anyone who may have been in the Stour Close area, or one of the neighbouring roads, who may have seen anything in connection with this incident, to come forward.
“No weapons have been recovered at this time and no arrests have been made yet in connection with this incident.
“I would like to reassure residents that there is a team of detectives working on this case and the local neighbourhood policing team will be stepping up patrols in the area. They will be happy to talk to any local residents about any concerns they might have.”
Anyone with information should contact Thames Valley Police via the 24-hour Enquiry Line on 101.
