The graffiti squad is asking for help identifying a man and woman in a tagging incident in the early morning hours of July 11.
The graffiti was sprayed on four properties in the 1400 block of Bingham Street on the South Side.
The tag is: AChizz23, in blue paint. Police think the same person left graffiti at the Serbian Club in the 2500 block of Sarah Street in December.
Anyone with information can leave a confidential tip with Pittsburgh Police.
