Officers in Lanarkshire and West Yorkshire believe they have uncovered a series of coded chalk symbols on walls and pavements – dubbed the 'Da Pinchi Code' - which criminals are using to send secret messages to burglars.
A previous list of symbols was published by West Yorkshire Police’s Facebook page for Pontefract and Knottingley, urging residents to report any chalk signs. “If you see any unusual markings on your home, low rise walls, pavement, kerbs or bins, take a photo, remove them and contact us,” the message read.
