OUTLAW bikies are believed to have put a $500,000 price on the heads of gang members who allegedly shot the son of a former Finks member.

Former Finks Bikie gang member Mark Sandery outside the Adelaide Magistrates Court.

South Australian police are aware of the offer, which leaves them in no doubt club members want to handle reprisals for the shooting of the 11-year-old without their intervention.

Mark Sandery's son was shot twice in the leg after armed intruders forced their way into a Semaphore house on Friday night. Police have received no co-operation from witnesses.

A source told Melbourne's Herald Sun: "The Finks are offering $500,000 to bring this bloke into any clubhouse in Australia. Every crook in Australia knows about it."

The Advertiser understands the Women's and Children's Hospital, where the boy is recovering, remains on high security alert, with some staff said to be terrified there could be further outbreaks of violence.
