The operation to clean up after a graffiti artist plaguing St Helens could cost thousands of a pounds, it has emerged.
The vandal, dubbed The Bulb after his distinctive but unsightly tags, is believed to be responsible for more than 200 incidents.
Council officials estimate the cost of removing each tag could range from £60 to £4,000 depending on a number of factors, including where it is and the size of the design.
CCTV cameras have captured an individual council officials believe is behind the spate.
A council spokesman said: “The individual captured on the footage was wearing a distinctive woolly hat and is believed to have access to considerable quantities of spray paint.
The poorly drawn symbols left by the vandal are usually in the shape of a light bulb and accompanied by the tag ‘bulb’.
“Most are created with spray paint, located randomly around the borough, but largely concentrated in the town centre – including Chalon Way, Duke Street, College Street and Central Library.
“Numerous examples have been found in Fingerpost, Peasley Cross and Delphwood Hollow.”
Anyone with information about the person responsible for this – or any other graffiti is being urged to call the Police on 101, Crimestoppers on 0800 555111 or St Helens Council on 01744 673114.
