Teignbridge Council is working with police to identify and prosecute the vandals who are attacking the park dubbed the district's 'jewel in the crown' of parks. Decoy, Newton Abbot, a former clay pit, attracts 225,000 visitors a year and underwent a major programme of investment in 2004 when state-of-the-art play equipment was installed. Last year, its was selected for entry into the national Green Flag scheme, an award managed by the Civic Trust on behalf of the government and which recognises Britain's outstanding open public spaces. But now the beauty spot has become a target for vandals who are setting fire to bins and ripping-up nature trail waymarker posts and throwing them into the lake. The latest damage, which occurred between Thursday and Sunday last week, will cost £250 to repair and is being treated as arson. Michelle Kenney, Teignbridge Council's communications manager, said there was an 'ongoing issue' with vandalism at the park and said rangers were working with the police to tackle it. 'We were disappointed to discover a further dog litter bin had been burnt-out at the end of last week, and that a new waymarker post had been removed,' she said. 'This follows damage to the other litter bins, the public loo block and various bird tables. While this vandalism is petty, there is a cost both to the local taxpayer and to the local environment. We are working closely with the police to monitor the area and the incident has been logged.' Miss Kenney added that a child's bike was found in the lake, possibly stolen, as it looked to be in good condition. The park rangers have it in safe keeping in case the owner contacts the police. Anyone with information regarding the offences should contact the police, quoting incident number JN/06/474.
