He was rushed to Alfred Hospital, where he remains in a critical condition six days later.

It’s believed the boy was at a friend’s home at the time of the shooting.

Police believe the shooting was accidental and are looking into who owns the gun and if the weapon was registered.

Authorities are not looking for anyone else in relation to the incident.

7NEWS understands the boy is well known to police and has a long history of violent offending.

He was one of three teenagers who ambushed Glen Eira student, Benjamin Phikhohpoom, outside his school in 2023.

Benjamin was dragged into a stolen car then moved from the moving vehicle, leaving him with life-threatening injuries.

Investigations into the incident at Seaford continue.
