Racist graffiti prompts council reward

Alice Springs Town Council is offering a $500 reward for anyone who comes forward with information about a recent spate of racist graffiti.

Mayor Fran Kilgariff says racial slurs have been spray painted on the road, footpaths and outside walls of businesses on Elders Street.

She says the content of the graffiti has far reaching effects on the whole community and will not be tolerated.
