A man was caught on camera vandalizing with graffiti the South Philadelphia home of Meek Mill’s grandmother Monday night, the rapper said.

In a video posted to Twitter on Tuesday, the rapper and criminal justice reform advocate shared security camera footage of a person spray-painting what appeared to be “ACORN” — which Mill described as “racial remarks” and “referencing white Privileged” — on a wall.

“A white man sprayed a racial remarks on my Grandmom’s house last night in south philly referencing white Privileged …” the Championships rapper, born Robert Rihmeek Williams, tweeted.

“The crazy part is this was a all black neighborhood 20 years ago It was gentrified and now this!” Mill wrote. “Just don’t let us catch you coward!”

Officers responded to a report of vandalism on the 700 block of South 18th Street on Tuesday morning, where at least one residence in the Southwest Center City neighborhood was defaced with graffiti, Philadelphia police said.

The matter is being investigated by the South Detective Division, police said. Anyone with information can contact South Detectives at 215-686-3013, or dial 911.

A representative for Mill didn’t respond to a request for comment.

This isn’t the only recent report of racial graffiti in the area. In November, Philadelphia police reported that a man in South Philly was targeting the neighborhood with white supremacist graffiti.

Mill is still tied up in legal wrangling after the Pennsylvania Supreme Court ordered his release from prison in April amid a high-profile battle over a probation violation.

In the months since his release, the rapper has gone from incarceration to reinvigorated eminence, releasing the Championships album and announcing a tour, headlining Jay-Z’s Made in America festival on the Ben Franklin Parkway, and leaning on his experiences to advocate for criminal justice reform.
