A man has been arrested after threatening graffiti was sprayed outside the home of Bristol mayor Marvin Rees.
Police said they were investigating criminal damage along with malicious and offensive social media posts.
In one incident, “Marvin Must Die” was sprayed on a pavement outside the family home of Mr Rees.
A spokesman for Avon and Somerset Police said: “Threatening graffiti was sprayed outside a property in the Greenbank area of Bristol overnight on Friday 11 January into Saturday 12 January.
“A 27-year-old man has been arrested on suspicion of racially aggravated harassment and he’s been released on bail with conditions until early February.
“The victim is being offered all the help and support they need.”
In an interview with Bristol Live, Mr Rees said his concern was for the safety of his family.
“I had to tell my boys what had been written and explain these sorts of things can happen but not to worry,” he told the website.
“The police have taken this very seriously and I am grateful to them for the speed and personal concern shown in their response.”
