Inner city residents have expressed their frustration after a bust of singer Luke Kelly was vandalised for the seventh time.
It was daubed with blue paint in the latest incident, leading to calls for the plinth it sits on to be raised.
"Following the last six times it happened, we have consistently said Luke should not be moved but protected," the North Wall Community Association said.
"This is now the seventh time it's happened, and while very much frustrating it's not unexpected.
"On behalf of the good, decent people of North Wall, the community association wish to apologise to Luke's family for the hurt and distress these incidents must be causing them.
"We are very proud of the fact that Luke was born and raised in North Wall and ask that these terrible attacks stop.
"We are calling for the powers that be to immediately protect Luke's statue or the eighth incident will surely happen."
There have been calls for the installation of tall spiked railings around the statue "which, if done right would not be unattractive", said the association.
Gardai said they were "investigating an incident of criminal damage to a statue on Guild Street".
A spokesperson said the incident was reported yesterday evening. No arrests have been made and investigations are continuing.
Any witnesses to the incident or anyone with information is asked to contact Store Street Garda Station on 01 6668000 or the Garda Confidential Line on 1800 666 111.
It is one of two statues of the musician that were unveiled in Dublin in January last year to mark the 35th anniversary of his death.
The carving of the stone bust was completed in Italy and is located opposite the corner of Guild Street and Sheriff Street.
President Michael D Higgins, who unveiled it, described Kelly as having "a unique ability to reimagine and reinterpret the traditional music which was experiencing a revival" during the 1960s and 1970s.
Kelly, who was born in 1940 and grew up in Sheriff Street, was one of the original members of The Dubliners, formed in 1962.
Among his best-known recordings was the haunting On Raglan Road.
