SYDNEY, July 26 AAP - Police are hoping CCTV images of a man wanted for questioning over the desecration of a Kokoda Track war memorial in Sydney will lead to an arrest. CCTV vision will be released on Tuesday as part of the investigation into the attack on the Kokoda Track Memorial Walkway, which links Concord Hospital and Rhodes train station in Sydney's west. The site was sprayed with graffiti sometime between Friday night and Saturday morning, and a number of CCTV cameras were also smashed. Rusty Priest, chairman of the Kokoda Track Memorial Walkway board, estimated a damage bill of $50,000. The NSW government stepped in to offer $10,000 for immediate repairs and said it would also cover the entire cost of restoration. Mr Priest, a former president of the NSW RSL, hopes the memorial honouring Australian soldiers' sacrifice in Papua New Guinea during WWII, will be "back in business" this week. On Sunday he described the incident as an "attack on Australia's history", saying veterans are struggling to grasp why anyone would want to damage what they see as a "living memorial. The memorial spans 800 metres with a centrepiece structure of granite walls and 22 stations that signify important battles fought in the New Guinea campaign during World War II. It has been a constant target of vandals since it opened in 1995. Police say the man in the CCTV footage may be able to assist with inquiries into the latest incident, and are urging anyone with information to contact Crime Stoppers on 1800 333 000.
