The steps on the northern end of Williamsbridge Oval Park were found smeared with graffiti the week of Feb. 18.
The scrawls make out what appear to be a “PF” stained on the family-friendly park’s left staircase facing north. It’s unclear when the markings first appeared.
The Department of Parks has stood on top of the graffiti issue, cleaning up a large graffiti-laden sign near the tunnel entrance.
Spurts of violence have crept up along the 19.75-acre park in recent weeks, including the shooting of a teenager.
