Police are trawling CCTV to try and trace culprits after offensive graffiti was scrawled near a public library and on park benches.
Police in Clayton-le-Moors said the graffiti is believed to have been drawn on Monday, May 16, and is located behind the library on Pickup Street and on benches at the Woodlands.
Pictures have been released showing examples of the graffiti. Some of it is too offensive to show.
There was a spate of graffiti in the area last November.
PC Paul Pountain, who covers the Clayton area, said: “We seem to have a spike in graffiti every few months.
“We posted something on Facebook last time and it calmed down. When it goes on Facebook they must get a bit scared and we are hoping this will now be the end of it.
“There is some quite offensive stuff, including bad language.
“We are now reviewing CCTV at the back of the library to see if we can find who is responsible for the criminal damage.”
Anyone with information call PC Pountain on 01254 353334.
