POLICE are appealing for information after yobs vandalised Corwen's bowling green by carving a 25 foot phallic symbol into the turf.  It's the second time such damage has been inflicted in a matter of weeks. And this time the vandals even carved a game of noughts and crosses into the green.  The first incident took place between 5pm on October 31 and 10am on November 1, with the second happening on the evening of November 6.  There has also been an incident of vandalism at the nearby football club where seats were damaged. Adrian Roberts, secretary of Corwen Bowling Club, said: “I was so disappointed when I saw the damage. “We have put so much effort into the bowling green, and the autumn remedial work-which includes reseeding and fertilising - cost us almost £1,200.  “When I saw what had been done I went there and rectified the damage as best I could, and I doesn't look too bad now, but only time will tell.  “It's very difficult to gauge at the moment and we won't know until the spring how it will look.  “It is upsetting that some people don't seem to realise how much work goes into the bowling green and think it's ok to inflict damage like this.  “In the summer months, the club offers free coaching to youths, and the door is still open for the people responsible to learn how to play the game rather than mindlessly damaging the facilities.”  A spokesperson for the Dee Valley Policing team said: “On Monday 31st October between the hours of 17.00pm and 10.00am on the 1st November, unknown persons have entered the grounds of the Pavillion Bowling Green on Green Lane in Corwen and have drawn offensive pictures into the lawn. “The lawn has recently had a lot of money spent on its upkeep.  “On the evening of 06.11.2016 offenders have entered the grounds of the Bowling Green, Green Lane and have drawn another offensive picture into the lawn. “This behaviour is not tolerated. “We urge anyone who may of seen or heard anything to please come forward. We will continue with our enquiries and will be conducting high visibility patrols in the area. “Any information please contact North Wales Police via 101.”  The images of the phallic symbols are too graphic to print.
