Vandals who damage Blackpool’s £100m sea defences were today warned they face prosecution if they are caught.
It comes after yobs daubed graffiti across a storm drain at Manchester Square.
Council workers have tried to clean up the eyesore.
North Shore resident David Booth who spotted the graffiti said he had been saddened to see the Promenade had been defaced.
He said: “Can you imagine if thousands of tourists saw the beach on the day I took these pictures, I doubt they would come back.
“As far as graffiti goes, more needs to be done to try to stop it and to clean it off as soon as possible.
“The council should always be looking out for things like that and make it known to the cleansing department that it needs attention.
“Maybe the community payback people can help clean the beach.”
The council said it was doing all it could to ensure the Promenade looked attractive for visitors and residents, and urged anyone who spots anyone carrying out graffiti to report it.
John Blackledge, the council’s Director for Community and Environmental Services, said: “It is extremely frustrating when people vandalise our sea defences.
“Not only do they provide a coastal defence for thousands of homes, they also look fantastic and are a huge part of the regeneration of the seafront that has taken place over the last 10 years.
“We have already attempted to clean the graffiti from the wall between incoming tides, however, the paint has permeated the stone and left outline shadowing.
“The area will be inspected following the next 24 hours to determine whether the tide has limited the residue of paint left or whether we need to paint the affected area.
“Anti-social behaviour, including incidents of graffiti, are criminal acts and those responsible could face prosecution.
“If anyone has any information about who carried this out, I would urge them to contact the police.”
