The rapper died in May, 2012, at the age of 47 after a battle with cancer, and the Palmetto Playground in Brooklyn Heights was subsequently renamed The Adam Yauch Park a year later in 2013.
After Donald Trump won the presidential election on 8 November (16), there has reportedly been a spate of racist attacks and incidents across the U.S., and the rapper's memorial park became the latest victim on Friday (18Nov16).
Swastikas, the symbol of Adolf Hitler's Nazi party, and the words "Go Trump" were spray-painted onto a children's playground in the park, which has been closed while authorities investigate the incident.
Yauch was a practising Buddhist, but his mother was of Jewish descent.
"Adam Yauch Park in Brooklyn Heights was left defaced with ugly symbols of hate today. This cannot be the new normal!" wrote one Twitter user alongside an image of the playground defaced with the racist symbols.
City councilman Brad Lander said the graffiti would be painted overnight, and posted details of a protest in response to the racist attack being held at the park on Saturday (19Nov16).
"Yet more hatred & anti-Semitism from Trump supporters. Swastikas on the playground equipment in Adam Yauch Park in BK Heights," Lander wrote on Friday.
"Adam Yauch is weeping for our country. Mom was Jewish. Practiced Buddhism. Spoke out against Islamophobia. Apologized (sic) for homophobic lyrics. NYPD Hate Crimes Task Force and @NYCParks staff on-site immediately. Will be painted over tonight. No place for hate. We will not be cowed," he added.
