Forensic experts in the North have examined 45 rifles in an attempt to trace the gun used in the shooting of a boy in a school playground.
Five-year-old Darragh Somers shot in the school playground at St Patrick's Primary School outside Enniskillen, Co Fermanagh, in Northern Ireland, last Friday at lunchtime.
He remains critically ill on a life support machine at the Royal Belfast Hospital for Sick Children.
Most of the guns examined were handed over by farmers who own land close to where Darragh was hit in the back of the head by a .22 bullet.
Ballistic tests have been carried out on all the guns in a bid to match them with a .22 bullet which was removed from Darragh's head. Police believe he was hit by someone shooting vermin in adjoining fields.
All the guns handed in are licensed and owned locally, although at least one belongs to a man who lives 15 miles away. They are being examined by experts at the police forensic science department at Seapark, Carrickfergus, Co Antrim.
Darragh's parents believe the shooting was accidental, but today police were still urging the person who fired the shot to own up.
Chief Inspector Nigel Kyle said: "They, like everyone else, want this confirmation that Darragh, or their family, were not deliberately targeted."
