AUSTRALIA COMPUTER STOLEN DURING ART THEFT Forensic tests in search for art thieves - National - www.smh.com.auSydney forensic experts investigating Australia's largest art theft have taken several items from the crime scene at a homestead in northern NSW for DNA and finger print tests.

While police are treating the reported $67 million heist as a serious crime, the investigation has yet to authenticate the true value of the stolen paintings, which are said to include Paul Cezanne's 1873 work Son in a High Chair, valued at $50 million.

Art experts have cast doubts over whether the missing painting is a genuine Cezanne.

Twenty paintings were among a range of goods stolen from the Limpinwood home of artist and art restorer John Opit between Saturday to Thursday last week.

Mr Opit also reported the theft of a saddle and a computer

Mr Opit reasons that he was not the victim of professional art theft because a $6,000 computer, oil paints, a saxophone and a saddle were also stolen.

Several valuable paintings were left behind.
