A home in Antigonish County was spray painted with racist graffiti some time Tuesday night, Nova Scotia RCMP say.

Police say a home and shed in Monastery were sprayed with profane and derogatory comments about aboriginal people. 

RCMP spokeswoman Cpl. Jennifer Clarke said Thursday that investigators have a suspect in mind but no one in custody. 

"It's not a random incident. It's not like an unknown person who's going through the community doing this," Clarke said, adding that police will not disclose what the graffiti says. 

Police are asking anyone with information to call the RCMP non-emergency line at 902-863-6500 or Crime Stoppers at 1-800-222-8477.
