A 16-year-old boy has been arrested for conspiring to murder a 17-year-old boy who was shot in a quiet cul de sac.
The 17-year-old was rushed to hospital with gunshot wounds after at least one shot was fired in the shocking incident just a mile from Royal Military Academy Sandhurst.
He was understood to have been hit on the right side of the chest by ball-bearings blasted from a BB gun at short range.
A 40-year-old man and a 34-year-old woman were also arrested on suspicion of attempted murder following the shooting in Blackwater, Hampshire.
All three, from Blackwater, have been quizzed by detectives from Hampshire Police.
Officers were called to Hearsey Gardens in Blackwater, where they found the 17-year-old with serious injuries.
Armed police and paramedics rushed to the scene just before 3pm after neighbours reported hearing a "loud bang" before being told to stay in their homes. A large police presence remained in the area as investigations continued.
The teenager was treated by paramedics before being taken to the specialist trauma centre at St. George's Hospital in Tooting, west London. He was said to be in a stable condition in hospital.
Detectives today appealed for witnesses to come forward to help establish the circumstances and events leading up to the shooting.
Chief Inspector Matt Reeves of Hampshire Police said: 'This was a very serious incident which has left a young man in hospital.
