Police hope forensic tests on a can of spray paint will reveal who vandalised a Douglas skateboarding park.
The area in Noble’s Park was daubed with offensive graffiti between 4pm on Monday and 8am on Tuesday.
Officers found a spray can containing yellow paint at the scene and this will now be subjected to forensic analysis.
Police say the graffiti was a mindless act of vandalism to a public facility and are urging anybody who knows anything about the incident to get in touch.
If you have any information you can contact police on 631212 or the anonymous Crimestoppers number, 0800 555 111.
