South Wales Police is investigating criminal damage to a mural in Cardiff Bay.
The damage is being treated as hate crime and officers are appealing for information.
Inspector Kevin Jones, from the Community Safety Department of South Wales Police, said: “The My City My Shirt mural was painted as part of a community project celebrating Cardiff as a diverse city and is a much-praised piece of art.
“It would appear that white paint has been deliberately thrown onto the mural from the pavement area where there are also splashes of paint.
“Understandably, local residents, the artist and Unify Creative, who commissioned the project, are very upset by what has happened to this mural which represents Cardiff as a proud, welcoming and multi-cultural city.”
The damage to the mural on James Street was reported on Monday, October 4 and is believed to have happened sometime overnight.
Enquiries are on-going and anyone with information is asked to contact South Wales Police quoting *348427.
