POLICE say they have made a "forensic breakthrough" in the hunt for the gunman who shot the 11-year-old son of a notorious former Finks bikie in October.

Crime Gangs Detective Inspector Paul Yeomans said evidence found inside the former home of convicted criminal Mark Sandery has put police a step closer to finding the armed men who broke in to the Milliary Rd house and shot the boy while he slept.

Det-Insp Paul Yeomans said forensic experts had searched the house for evidence several times since the shooting.

The intruders burst in and fired two shots through the doorway, both bullets hitting the boy in the leg. He later had surgery in hospital.

Sandery was not home during the attack and later refused to co-operate with police. He publicly vowed to take revenge for the shooting, saying: "We'll find you, you f***ing dogs. You hurt kids . . . you'll see what happens to you."

The shooting sparked fears of a bikie war and reprisals, which were later dispelled by senior Finks members.
